That's it from this live text.
Head on over to our main live to get all the reaction while I pick the bones out of that finish.
That's a huge point for Hull, who more than deserved it, having kept Saints at arm's length all afternoon.
It's was a 50-50 call from Mike Dean on the penalty but referees have been asked to clamp down on shirt pulling and holding.
Fortunately for Marco Silva, his keeper stepped up and delivered.
A remarkable finish to a previously uninspiring game.
A vital point for Hull.
Jakupovic the hero.
What a breathless finish.
Oh my days, it's a goalline clearance.
The corner wriggles its way through to Oumar Niasse but he can't quite bundle it home as Cedric heads it away just in front of the line.
More has happened in the last five minutes than the rest of the game combined.
The Hull fans in terrific voice now. What a clutch moment from Jakupovic. Stirring stuff.
Can Hull snatch three points even? They've got a corner at the death...
WHAT UNBELIEVABLE SCENES!
Dusan Tadic drills it low towards the bottom right but Eldin Jakupovic extends his long limbs to save the strike.
Marco Silva goes mental on the sidelines.
Sunderland are still going down!
Bournemouth score, seemingly relegating Sunderland.
Then Mike Dean gives Southampton a penalty against Alfred N'Diaye for holding on to Yoshida.
Dusan Tadic to take...
Oh my word! Out of nowhere, a massive swing one way then back in the Premier League survival race!
Lazar Markovic off for Michael Dawson.
Both sides settling for a point?
Final roll of the dice for Southampton as Nathan Redmond is replaced by Jay Rodriguez.
Sam Clucas is back on his feet.
Hull appealing for a backpass here as Fraser Forster picks up the ball with Oumar Niasse looming.
Looked more like a miscontrol from Jack Stephens than an intentional pass though.
Inside the last five minutes. Sam Clucas is down and requiring treatment.
Oh Oumar that was the chance!
A long ball forward is guided down by Markus Henriksen straight into the path of Niasse but he blasts his effort miles over.
Great work from Eldin Jakupovic as he makes up for a weak punch away from the corner by closing down Dusan Tadic to block the goal-bound shot, before Hull get in another key block on Josh Sims.
Ten minutes or so to play, Hull heading for a rare away point.
Another terrific tackle from Harry Maguire to deny Southampton as the hosts get in round the back - Nathan Redmond was ready to pounce there.
Hull clear the Saints corner but the hosts come straight back at them and win another.
Shane Long threatening down the left but the substitute just sees the ball nipped off his toes before he can get off a shot.
Grosicki's wicked delivery is headed goalwards by Harry Maguire, who feels he was fouled by Jack Stephens - Mike Dean not interested though.
Oumar Niasse prevents the ball going out until to then dribble it over the byline for a goal-kick with no Hull player in assistance.
Nothing doing from that one but Elmohamady has won another corner for Hull...
Kamil Grosicki has been a rare bright spot in this game as the Pole's drive deflects off for a Hull corner...
Hull make their first chance of the game as Evandro is replaced by Markus Henriksen.
No. No, they can't.
Dusan Tadic's delivery is easily caught by Eldin Jakupovic.
Southampton may have gone to the beach some time between Tuesday's defeat to Chelsea and this one.
First booking of the game and Harry Maguire gets his money's worth with a clattering challenge on Shane Long.
Can Saints fashion something from the free-kick?
Only Sunderland and Middlesbrough have scored fewer goals at home this season than Southampton.
They don't look much like improving on their current tally of 17 here.
Dusan Tadic is the latest Saints man to try his lucky with a shot from outside the area.
Dusan Tadic is the latest Saints man to get his shot nowhere near the target.
Hull have had the only shot on target of the game.
Sam Clucas takes a free-kick from deep - Hull again use Harry Maguire as a focal point at the back post, the captain winning yet another header back across the area but yet again Southampton are wise to it and win the second ball.
The first half was intriguing, at least. This has been pretty poor since the break though.
Finally a burst of life in this second half as Andrew Robertson strides into the Southampton area but the left-back's reverse pass finds a red-and-white shirt instead of a black one.
Not the best of clearances from Andrew Robertson as the ball falls to Steven Davis but the Saints captain can't quite wrap his foot round the ball enough to keep his shot down.
And it's Josh Sims on for Sofiane Boufal, with Shane Long replacing Manolo Gabbiadini.
Saints' costly pair had looked underwhelming out there - time for a bit of a youth and a burst of pace.
Nathan Redmond comes forward and unleashes a shot well over the bar.
Looks like Claude Puel has seen more than enough - a double change is coming...
Having said both sides are coming forward, it's all settled down again.
Here's something perhaps?
Kamil Grosicki looks to get in behind but is ruled offside...
...on the replay it looks like the Pole was level and would've been well positioned to get a shot off.
Oumar Niasse drills a low ball from the right across the face of goal and Fraser Forster has to be quick to smother the ball before Kamil Grosicki can nip in.
Both teams looking to come forward and grab an early second-half goal.
Nice turn from Dusan Tadic as he finds Nathan Redmond and then gets the ball back but his shot is deflected wide, before Hull clear from the corner.
Hull look to get in down the Southampton right but Jack Stephens does really well to guide Lazar Markovic off the ball and clear.
Southampton nearly have a great chance to go ahead as Cedric is free on the right, his cross finding an unmarked Sofiane Boufal on the edge of the area.
Boufal skips past one tackle - he may have got a penalty had he gone down - only to have Harry Maguire take the ball off his toes with a wonderfully-timed tackle to prevent the Moroccan getting a shot off.
Harry Maguire of all people strides forcefully out of defence, ball at his feet, trying to spark an early Hull attack.
Southampton are alert enough though to prevent the visitors getting in a decent delivery and finally smother the ball away from them.
Here we go again.
Right, the teams are back out on the pitch and we'll soon be back under way.
Prior to kick-off at BBC Sport towers we were discussing the most incident-free Premier League games this season (top of that sorry pile is Crystal Palace 1-0 Watford on 18 March by the way).
Well three of the four 3pm kick-offs are making an unwanted bid for consideration in that category so far.
At least Kamil Grosicki hit the post for Hull here. Not much else to report though.
You don't even need to be a football team to play in the FA People's Cup.
LBoro Rangers are a group of university students who are taking part in the Higher Education category......
"I think we're going to make it, I think we're going to save it yet."
Feeder's Buck Rodgers belts out at St Mary's as the players depart down the tunnel, providing a potentially apt message for the Hull players.
They've looked the better side here but lacking a vital goal. Don't forget - if they better Sunderland's result they'll relegate the Black Cats, who are currently also drawing 0-0 with Bournemouth.
Southampton were met with a smattering of boos on the whistle. It's not been dire from them but a little lifeless.
The corner finds its way to Sam Clucas on the bottom right of the area but his curling shot is blocked.
Hull work it left to Kamil Grosicki but his shot from distance is easily gathered.
And that's your lot for the first half. Tepid.
