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.
- Semi-final draw - Inverness CT or Raith v Dundee Utd or Celtic, Falkirk v Hibs
- QF: Dundee United 1-1 Celtic
- QF: Hibernian beat Berwick 4-0 at Easter Road
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.
