That's it from me then folks, thanks very much for your company and be sure to join us again on Tuesday night when Inverness Caley Thistle face Raith Rovers in a rearranged Scottish Cup quarter final.
It's been some day of Scottish Cup quarter-final drama in Edinburgh and Dundee.
Hibernian booked their semi-final spot with a 4-0 win over Berwick Rangers, before Dundee United and Celtic drew 1-1 at Tannadice in as dramatic a game as you'll see in a while.
The semi-final draw was also made and Hibs will face Falkirk, with Inverness CT or Raith Rovers meeting Dundee United or Celtic.
"It was strange that the initial challenge didn't get dealt with by the referee. The initial challenge on Nadir was a bad one.
"I feel sorry for Paton, but I'm proud of the players, how they responded.
"Absolutely (we will appeal the red card) as Paul Paton was not involved in the incident.
"I don't think he (Aidan Connolly) dived. I think Anthony Stokes' thigh has put him down."
"We should've won. We had the chances to win but sometimes you're not effective enough.
"I haven't seen the first sending offs, but the other one is very clear.
"It was a dive (United penalty) in my opinion.
"We have to be happy we are still in it and we're going to have some exciting games coming up."
"The sending offs were a bit harsh but that was the referee's call. The penalty looked soft.
"After Paul Dixon was sent off it was one-way traffic. I was disappointed to miss the penalty but I tried to put the header in the corner and thankfully it went in.
"We went in 1-0 down and were very disappointed with that. I'm just delighted I scored and kept the team in the Cup."
The draw is made for the semi-final, with the ties to be played on the 18th and 19th of April.
Inverness Caledonian Thistle or Raith Rovers v Dundee United or Celtic
Hibernian v Falkirk
The draw for the semi-finals is imminent...
We're hoping to get some post-match reaction from Tannadice soon, and it'll be interesting to hear what the managers made of today's match.
To recap the headlines of a day of Scottish Cup quarter-final action - Hibernian saw off Berwick Rangers 4-0 at Easter Road and Dundee United drew 1-1 with Celtic at Tannadice.

Referee Craig Thomson and his team of officials are sure to be the subject of much talk tonight after their performance at Tannadice. One red card that was a clear case of mistaken identity, another that was dubious, and a contentious penalty.
We'll soon have the draw for the semi-finals, with only Falkirk and Hibernian assured of a last-four spot at this stage.
The upshot of today's game means Celtic and Dundee United will play four times on the spin.
If there's as much drama in the next three games as there was in this one, it could be a very interesting few weeks.
Where do you start with that one?
The full time whistle goes to end an action packed Scottish Cup quarter final tie at Tannadice.
Celtic's Nir Bitton goes off after picking up an injury and Darnell Fisher comes on.
As it stands, these sides will meet for the fourth time in a matter of weeks with this match going to a replay.
We have five minutes of stoppage time at Tannadice...
Nir Bitton plays in John Guidetti but the Celtic striker's first touch isn't the best and Dundee United keeper Radoslaw Cierzniak spreads himself brilliantly to make the stop.
Celtic are continuing to try to build the play from deep and as John Guidetti gets into the box he has a chance to deliver, but his cross is easily collected by Radoslaw Cierzniak.
Celtic make another change and it's Stefan Scepovic who comes on for Leigh Griffiths.
Dundee United have had a few free-kicks in the last 10 minutes and their delivery has been woeful on every occasion.
Celtic's James Forrest knocks the ball into the box for John Guidetti, but his right-foot shot is well over the bar.
We're into the last 10 minutes at Tannadice and Celtic are pretty much camped out in the Dundee United half. Can they find a winner against the nine men of United?

Celtic's Leigh Griffiths produced an excellent header to make it 1-1 at Tannadice.
Midfielder Nir Bitton tries an effort from outside the box, it moves in the air but it drifts wide of the Dundee United goal.
Celtic's John Guidetti goes down the left and floats a ball into the box, it looks destined for the head of Leigh Griffiths but Radoslaw Cierzniak leaps out and snatches it.
Dundee United are facing a tough last 15 minutes with only nine men. Their defence is holding out for now, but it's all looking a bit disjointed for the hosts.
Jack in Edinburgh: "What an appalling performance by the officials. How can Craig Thomson continue as a Grade One referee after this?"
Dylan from Shetland: "What a game! What's the odds for a 4th red card?"
Leigh Griffiths makes up for his earlier penalty miss with a sensational header to haul Celtic level. Stefan Johansen provides the perfect delivery and Griffiths plants a brilliant header into the bottom corner.
Celtic sub John Guidetti has a chance but his close-range effort from the angle is saved by Radoslaw Cierzniak.
It's all-action now folks...
Celtic have Dundee United pegged back but the hosts break upfield and Calum Butcher races into the box, only to see his shot is saved by Craig Gordon.
Celtic manager Ronny Deila makes a change with Anthony Stokes off and Swedish striker John Guidetti on.
United then make a change, Ryan Dow is off and Chris Erskine is on.

Celtic striker Leigh Griffiths takes the penalty and Radoslaw Cierzniak makes a brilliant save to his left.

Celtic get the second half under way...

Dundee United's Paul Paton was bemused, to say the least, after being sent off early on.
Alan in Eyemouth: "If Craig Thomson is supposed to be our best ref then god help us! The red cards were a yellow at best, he then sent the wrong player off & then a total dive at the penalty. Scott brown should have at least got a yellow card for his 4 fouls. Total joke."
John in Glasgow: "Talk about a bad day at the office, this is an unbelievable performance from the officials and that penalty is a clear dive in front of Craig Thomson and he sees that as a penalty......very poor indeed."
Joe on Twitter: "Ref is having an absolute mare in this one, neither were sending offs and penalty was an outrageous call COYBIG."
Well, that was some first half. Early drama and late drama, with some very ordinary stuff sandwiched in between.
There's no doubt there was a case of mistaken identity as Paul Paton was red carded early on, and Virgil van Dijk didn't appear to do much wrong either, but he was still sent packing.
Then came the late penalty and our colleagues on BBC Radio Scotland are suggesting TV pictures show that Aidan Connolly took a dive under the challenge of Anthony Stokes.
Plenty to mull over then...
Dundee United hit the front as Nadir Ciftci fires home the penalty kick. The Celtic players are furious with referee Craig Thomson, they are convinced Aidan Connolly was not touched...
Aidan Connolly goes down under the challenge of Anthony Stokes and Craig Thomson awards a penalty.
Celtic race up the other end and Stefan Johansen plays in Anthony Stokes, but his shot comes off the post. It looked like a poor effort but the pitch may well have played a part.
United's Calum Butcher takes a shot from the edge of the box, it's going wide but Ryan Dow redirects it and the ball comes back off the inside of the post.
Celtic's Stefan Johansen is a lot closer with this effort as he drives in a shot from 30 yards that almost catches Radoslaw Cierzniak out, the United keeper does make the save though.
Emilio Izaguirre knocks the ball into the box and Stefan Johansen tries an overhead kick, but the Celtic midfielder gets it all wrong and the ball falls to Sean Dillon, who clears his lines.
We're heading into the last five minutes of the first half and other than that early red card incident, there hasn't been a great deal to get excited about.
Jim in Netherlee: "You seriously wonder about officials. Paul Paton was actually nearer Dens during the incident!"
Pete: "Please can we have video refereeing?"
Stephen Hay on Twitter: "Dundee Utd need to take some of the transfer money and pay a groundsman. A disgraceful pitch for a showcase game."
Dundee United's Ryan McGowan gives up possession to Anthony Stokes and he breaks away, but his attempted pass to James Forrest is poor and the chance is gone.
BBC Radio Scotland pundit at Tannadice
"It's a poor game of football and both teams are capable of much, much better. The ball is up in the air and there's no pattern to the game. We're hoping it will settle down and we'll get a game of football."

Dundee United and Celtic are both down to 10 men after Paul Paton and Virgil van Dijk were red carded early on. It's unlikely we've heard the last of this one though.
Scott Brown makes a brilliant tackle to deny Aidan Connolly a shot at goal but the Celtic skipper then commits a foul on the edge of the area. United's Nadir Ciftci tries to pass the ball into the net from the free-kick but it goes harmlessly wide.
The hosts play some nice stuff on the edge of the Celtic area and earn a corner, but Nir Bitton clears the danger.
It's all a bit scrappy at Tannadice.
There could be a major knock-on effect from those two early red cards as Paul Paton and Virgil van Dijk will miss next Sunday's League Cup final.
Of course, there is every chance of an appeal from both sides. And you would fancy they might have some joy given the circumstances.
United's Ryan Dow races through on goal but the Celtic defence catch up with him and his effort is easily saved by Craig Gordon.
A bizarre moment at Tannadice as both sides are reduced to 10 men. Paul Paton was certainly unlucky to see red as he had nothing to do with the incident, and Virgil van Dijk will also feel hard done by.
There's a flashpoint in midfield involving Celtic's Scott Brown, United's Calum Butcher and Virgil van Dijk. Brown had the initial challenge but there seemed to be a reaction from the United man.
Referee Craig Thomson then flashes a red card at United's Paul Paton, who was not involved in the incident, and Virgil van Dijk, who seemed to do very little.
Dundee United's Ryan McGowan takes out Anthony Stokes with a late challenge, just outside the box, but the free-kick is cleared by John Rankin.
The pitch is very poor in places and passing won't be easy today.
Celtic look to make a fast start as Leigh Griffiths gets away down the right but his cross is easily cleared.
Dundee United get us going at Tannadice
The teams are out on the pitch...
Kick-off is fast approaching at Tannadice...
Celtic manager Ronny Deila has made no secret of the fact he's chasing the treble this season. Today is one of the hurdles standing in his side's way as they look to achieve that feat.
Joe from Fife joins the debate on James Forrest: "As a Celtic fan I have to say that James Forrest has been a nightmare every game I've seen him in since Barcelona. He's a nice young man - but he has not beat a defender or played a good ball for very many games."
The draw for the semi-finals of the Scottish Cup follows this match at Tannadice. Falkirk and Hibernian are already in the hat, who will join them?
James Forrest is in the Celtic line-up today and his form this season is being debated by our colleagues on BBC Radio Scotland. The consensus is the winger has struggled to find his best form this season and may find it tough to oust Gary Mackay-Steven from the starting line-up, when the former Dundee United man is not cup-tied of course.
It could be big day for Forrest then...
Celtic manager Ronny Deila
"It's going to be a tough game and a good game, hopefully we'll be the better team.
"We have to learn from everything we do and we're very hungry to bounce back today. The energy should be back again and we know how good we can be.
"The pitch is not the best so we need to be quite direct as well. We have a plan for it."
The state of the pitch at Tannadice is causing both managers concerns...
Dundee United manager Jackie McNamara
"Going by the state of our pitch, I think there will be a lot of mistakes made. We need to be more compact, in helping each other. The last couple of games we haven't helped ourselves with doing straight passes. We need to adjust for the state of the pitch. I feel in certain areas we need to have a better shape. Aidan (Connolly) has been excellent and Dow coming off the left will cause them problems and Nadir (Ciftci) will hopefully give the same performance as he did when we beat them in December."
Dundee United: Cierzniak, McGowan, Dillon, Fojut, Dixon, Paton, Butcher, Rankin, Dow, Ciftci, Connolly. Subs: Souttar, Erskine, Bilate, Telfer, Spittal, Szromnik, Anier.
Celtic: Gordon, Ambrose, Denayer, van Dijk, Izaguirre, Brown, Biton, Forrest, Johansen, Stokes, Griffiths. Subs: Guidetti, Scepovic, Zaluska, Wakaso, Fisher, McGregor, Henderson.
Referee: Craig Thomson
Berwick player-boss Colin Cameron spoke to BBC Radio Scotland after his side's 4-0 defeat at Hibernian...
"The scoreline is a wee bit harsh. We started well, created a few chances and it was pretty even I felt. The two goals in quick succession gives them confidence and the it's an uphill struggle for us.
"The third goal was always going to be the important one and when Hibs got it the game was killed off.
"We did play some good stuff at times but we never turned our better spells into goals. The mistakes we made we got punished for. We've got to take a lot of credit from getting to the quarter finals."
Celtic go into today's game on the back of a 1-0 defeat to St Johnstone on Wednesday night.
Before that they were in excellent form and are looking to get back to winning ways at Tannadice. They do, however, know how dangerous Dundee United can be.
The Tangerines beat Celtic 2-1 at Tannadice in December, although United had Gary Mackay-Steven and Stuart Armstrong then, who have now moved to Celtic. Both are cup-ties for today's game.
"The important things is we're in the hat for the next round. Berwick did great and this was their day, all the credit goes to them because they've done fantastically to get to this stage.
"It's always important that you don't give the underdogs any impetus. We've done the job and we can now see who we will get later on.
"We've got a good balance, with very intelligent footballers who are hungry and have points to prove. Scott Allan can do unbelievable things but he can also frustrate you, and I'm prepared to put up with the frustrating things.
"I'd like to stay clear of Celtic. Whoever we play it will be tough, but we will be tough for them as well, no-one will want to play us either."
The home side are going into today's game on a dreadful run of form.
They have gone four games without a win, with their last victory coming in the last round of the Scottish Cup against Stranraer.
Dundee United and Celtic meet in the first of three huge games between the sides.
Following this Scottish Cup quarter final, it's the League Cup final next Sunday and then they meet in the Premiership.
We'll get some reaction from Easter Road shortly, and we'll now look ahead to Dundee United v Celtic at Tannadice.
It was a convincing performance from the Easter Road side. with Jason Cummings and Lewis Stevenson on target in the first half and Sam Stanton and Liam Fontaine adding goals after the break.
They join Falkirk in the draw for the last four, which will be held after Dundee United entertain Celtic at Tannadice.
Our colleagues on BBC Radio Scotland are wondering if 2015 could be Hibs' year to end their 113-year wait to win the Scottish Cup...
Referee Bobby Madden brings the match to a close and it's Hibs who go into the draw for the semi-final.
We're into two minutes of stoppage time at Easter Road...

Defender Liam Fontaine nodded home Hibs' fourth goal of the day.
Jonny Fairbairn earns an angry look from keeper Billy Bald. The defender's short passback almost lets Franck Dja Djedje in, but Bald gets their first to clear.
A worrying moment for Hibs as David Gray lands awkwardly after an aerial challenge. He walks off the pitch rather gingerly.
Berwick's Andy Russell comes off and Blair Henderson takes his place.
Billy Bald's excellent stop led to a corner and from Sam Stanton's delivery, Liam Fontaine is unchallenged as he nods the ball into the net. The keeper maybe should have come for that one.
Jason Cummings and Sam Stanton link up to release Liam Craig on the left and his effort is saved brilliantly by keeper Billy Bald.
Franck Dja Djedje is on for Hibs, in place of Dominique Malonga.

Sam Stanton was only on the pitch for a few minutes when he knocked in Hibs' third goal. No wonder he's smiling...
We're into the last 15 minutes of this quarter final and barring a miracle for Berwick, Hibs will be taking their place in the last four of the Scottish Cup.
Murdo MacLeod at Easter Road
"The Berwick players are struggling a bit now, their legs are going but their attitude is keeping them in the game."
Berwick's Lee Currie goes off and Scott Maxwell comes on, while Hibs' Dylan McGeouch makes way for Liam Craig.
Hibs' Jason Cummings fires in a free-kick from 25 yards and Billy Bald makes a decent diving stop.
Berwick are struggling to get into the Hibs half here...
Dylan McGeouch plays in Dominique Malonga on the left and again his effort is saved by Billy Bald, but this time the ball breaks to Sam Stanton and he applies the simple finish. Some first touch for sub Stanton...
Hibs' Jason Cummings feeds Dominique Malonga on the right and he fires in a low effort that Billy Bald saves well, and Jonny Fairbairn completes the clearance with an excellent diving header.
Sam Stanton takes Scott Allan's place in the Hibs ranks and Berwick take off Ross Gray, with Darren Lavery on.
Berwick's Lee Currie picks up the first booking of the game for an uncompromising challenge on Dylan McGeouch.
Scott Allan drills a corner into the Berwick box and after a header back across goal, David Gray nods against the post.

Murdo MacLeod at Easter Road
"Hibs have not started in the second half. It's been all Berwick so far."
Early chance for Berwick as Steven Notman plays in David Gold, who produces a great piece of skill to lob the ball over Paul Hanlon and then fires in a shot but it's easy for keeper Mark Oxley.
Neither side have made any changes at the break.
Hibernian get the second-half underway...
The teams are back out on to the pitch at Easter Road...
Murdo MacLeod at Easter Road
"Mark Oxley has not looked comfortable and Berwick have given the Hibs defence a few awkward moments."
Remember we're off to Tannadice after this game for what should be cracking Cup tie between Dundee United and Celtic.
Championship outfit Hibs are two goals to the good against their League Two visitors, with Jason Cummings and Lewis Stevenson on target in an entertaining first half.
The whistle goes and it's been a productive first half for the home side.
It's Berwick's turn to threaten as Lee Currie collects the ball on the left, just outside the Hibs box, and fires in a left-foot shot that drifts narrowly wide. Keeper Mark Oxley looked worried about that effort.
Hibs go close again as a David Gray meets a corner to the back post, but the full-back's header comes off team-mate Liam Fontaine and goes wide.

Jason Cummings gave Hibernian the lead with a neat low finish under Billy Bald.
With around five minutes of the first half left, Berwick are trying to find a way back into this game. They look good going forward but so do Hibs...
Hibs get a free-kick just outside the box but Scott Allan's effort is tame, and proves no problem for Billy Bald.
Paul: "As a Celtic fan, I always liked Alan Stubbs' commitment and passion as a player. As a manager though, he is a pleasure to listen to. Very open, honest, and funny with it. Hibs' problem might be hanging onto him."
Tom in Edinburgh on Twitter: "It's taken a few years, but Stevenson is becoming some kind of Hibs legend."
A moment of slackness from Hibs' Scott Allan gives Paul Willis a shooting chance and his dig from distance goes just wide.
It's almost 3-0 as Dominique Malonga cuts in from the left and unleashes a shot that takes a deflection and goes out for a corner. Straight from Scott Allan's flag kick, Fraser Fyvie tries a first-time effort that goes just over the bar. Troubling times for the visitors.
It could be a long day for Berwick Rangers. Lewis Stevenson shows tenacity to pick up the ball on the edge of the Berwick box, he plays a neat one-two with Dominique Malonga and then finishes well beyond Billy Bald.
Lewis Stevenson charges down the left and plays a delightful angled ball into the path of Jason Cummings, who shows great composure to knock the ball beyond the onrushing Billy Bald.
Hibs midfielder Scott Allan is starting to move through the gears, going off on a mazy run through a host of Berwick defenders. He is eventually stopped but the visitors will have to keep a close eye on the creative midfielder.
Panic takes hold in the Berwick box after Scott Allan whips in a dangerous free-kick, but the defence eventually hacks it clear.

Ross Gray earns Berwick a corner as he plays the ball off Lewis Stevenson.
Scott Robertson tries to feed Jason Cummings with a nice reverse pass into the Berwick box but it's just out of the striker's reach.

Berwick get the first sight of goal as Paul Willis crosses the ball into the box and David Gold tries a header, but is goes well wide of the target. Might have done better there.
Berwick Rangers get us underway at Easter Road...
The teams are in the tunnel at Easter Road...
It's almost kick-off time on a marathon day of Scottish Cup action...
And remember, the draw for the semi-finals of the Scottish Cup will be made after today's games.
Falkirk have booked their place in the last four thanks to Friday's 1-0 win at Queen of the South, while Inverness Caledonian Thistle and Raith Rovers will meet on Tuesday night after Saturday's game fell foul of a waterlogged pitch.
We're just about five minutes before kick-off at Easter Road...
Colin Cameron, who is unable to take his spot in the Berwick line-up due to a thigh strain, spoke to BBC Radio Scotland....
"There was a chance I could have made it but I felt I really had to be 100%. We have 10 important league games after this today but I'm confident the players will go out and give me their all.
"I've been involved at Hearts and Raith Rovers when we were underdogs going into cup games and we've won. We need to play out of our skin.
"Darren Lavery is suffering a bit because we've had a change of formation. We're going to try to flood the midfield today. Hibs' two full backs love to bomb forward so maybe we can exploit that. We'll try to hit them on the counter attack.
"It's been 35 years since Berwick were last in the quarter-finals of the Scottish Cup and the players will be doing their best to give the fans something to cheer about.
"It's what the Scottish Cup is all about - so-called smaller clubs having the chance to be giant killers, and today's no different."
"We're not contemplating losing the game. We have a brilliant opportunity to go through but we have to approach the game like we did for the last 25 games. We know what the Cup's like, Berwick are going to be nervous and we have to capitalise on that.
"It's been a collective team that's turned it around, the players, the staff behind the scenes, and at this moment we're getting the results. This is a game to put us into the next round, we're not looking too far ahead.
"We're on the right track and we honestly believe we have a chance of both (Scottish Cup and promotion).
"We have energy, quality, a team that can score goals and we don't concede easily."
We're just about to hear from the managers ahead of today's first game...
Hibernian: Oxley, Gray, Fontaine, Hanlon, Stevenson, Robertson, Allan, McGeouch, Fyvie, Cummings, Malonga. Subs: Forster, Craig, Stanton, Handling, Dja Djedje, Cerny, Martin.
Berwick: Bald, Jacobs, Young, Fairbairn, Drummond, Gray, Currie, Notman, Willis, Russell, Gold. Subs: Maxwell, Bauld, Dargo, Andrews, Lavery, Miller, Henderson.
Referee: Bobby Madden.
The odds are stacked against Berwick but it is the Cup after all, shocks can happen.
And what a sweet win it would be for Berwick player-boss Colin Cameron, who starred for Hibs' Edinburgh rivals Hearts for seven years, scoring more than 45 goals from midfield in more than 160 games.Copyright: SNS
And when you talk about Scottish Cup shocks, Berwick are one of the teams who have their own piece of history. They beat Rangers 1-0 in the 1967 Scottish Cup - one of the biggest shocks in the competition's history.
The team lines are on their way...
To find the last time these sides met in the Scottish Cup you have to go back to 1980, and again Hibernian came out on top - 1-0 after a replay.
See Hibs fans, not all history has to be painful...
The last time Hibernian and Berwick met was in the Scottish League Cup in 2011, when the Edinburgh outfit battered the Wee Gers 5-0 at Easter Road.Copyright: SNS
Martin Scott scored a double the night Hibs beat Berwick 5-0 in the Scottish League Cup.
Berwick have never won the competition, in fact, they have never reached the last four, so today offers Colin Cameron's side a chance to write their own piece of history.
And now for the painful part for Hibs fans...
Any time Hibernian make inroads in the Scottish Cup their long wait to lift the trophy inevitably comes up.
It's now 113 years since they won the competition, when an Andy McGeachan goal gave them a 1-0 win over Celtic in Glasgow.
The club's fans are probably sick of wondering if this might be their year. But could it be?
Berwick are on the opposite end of the form scale and have not won a game since beating Lowland League side Spartans 1-0 in the last round of the Scottish Cup.
Colin Cameron's outfit are struggling in League Two and are sitting second bottom of Scotland's fourth tier.
The Easter Road outfit reached this stage of the competition thanks to a come-from-behind 3-1 win at home to Arbroath.
Hibernian go into today's quarter-final in fine form, having won their last four matches in all competitions.
Alan Stubbs' side are sitting second top of the Championship table and are playing some nice stuff.
Dundee United against Celtic is the tie of the round for a host of reasons but we'll focus on Hibernian and Berwick for now...
It's all set to be a busy day of action and we want to hear from you...
