- Hull unbeaten in last seven home games in all competitions
- West Ham have suffered three straight league defeats as part of a five-match winless run
- Snodgrass starts for West Ham against former club
Six minutes of injury time are to be played.
I've spent a lot of today describing injuries to Hull players and we have another one.
Eldin Jakupovic is down on this occasion, the Hull goalkeeper taking a hefty whack from Andy Carroll as he went up for the ball.
He's rolling around in some discomfort but makes a swift recovery.
The turnaround is complete!
You can't say Hull deserve it because they have been a long way from their best today, but on the balance of play in this second half you cannot begrudge them the lead.
Kamil Grosicki's corner is an inviting one and Andrea Ranocchia pops up at the near post to guide a header into the far corner.
A huge, huge goal in Hull City's season.
Shaun Maloney forces a corner for Hull.
Hope for the hosts.
Scrappy again from Hull. They had the West Ham defence under real pressure again but could not play the right pass at the right moment.
Markovic and Henriksen were the guilty parties on this occasion, passing the ball between themselves with no clear direction before Henriksen flashed the ball across the face of the goal and away.
Double change for Hull.
On come Markus Henriksen and Shaun Maloney. Alfred N'Diaye and Abel Hernandez make way.
Harry Maguire executes a great sliding challenge to stop Arthur Masuaku in his tracks but gets up holding the back of his thigh.
Hull do not want to lose him, and he will not want to go off with England manager Gareth Southgate in the stands.
Alfred N'Diaye is the latest into the book. It's not been a dirty game but Mike Jones has still managed to dole out four cautions so far.
Persistent offending appears to be N'Diaye's crime.
West Ham have drawn the sting from Hull here. The Hammers are growing back into the contest now as Hull's momentum after the goal subsides.
Another change for West Ham, this time because of injury, as Arthur Masuaku replaces Aaron Cresswell.
Robert Snodgrass is taken off by West Ham.
He doesn't look happy. Hull fans are delighted.
Edimilson Fernandes comes on.
Andy Carroll into the book for West Ham. It's for handball as he went to ground but it's a very soft one.
Are Hull going to rue these missed chances?
They've just had three glorious opportunities to go in front, first when Lazar Markovic failed to play in Oumar Niasse for a simple finish and then with two chances in quick succession that should have been taken.
First the ball broke to the unmarked Alfred N'Diaye but he contrived to hit the post from eight yards. The follow-up fell to Kamil Grosicki - again from around eight yards - but he fired wide.
Harry Maguire also goes down moments later in the area to a few half-hearted penalty appeals, but there's nothing doing.
Oumar Niasse goes into the book for Hull. He went in heavily on Jose Fonte after the ball had gone and can have no complaints.
Delight for Hull it may be but West Ham are pushing to retake the lead. Another deep cross goes over the head of the Hull defenders and Andy Carroll - who else? - is there at the back post to head straight at Eldin Jakupovic.
Former England full-back on Final Score
Robertson has been marauding forward all game and it was a great finish! A striker's finish from the left back.
A lovely Hull goal and it's a first Premier League goal for Andrew Robertson.
Lazar Markovic started the move with a bright cut inside and an exchange of passes with Alfred N'Diaye. Markovic worked the ball out to half-time substitute Kamil Grosicki who played a lovely weighted pass into the path of the advancing Robertson, who continued his run into the box and fired low past Darren Randolph.
A really good goal.
Ranocchia's first act after coming back on is to aimlessly punt the ball out of play, straight to the feet of manager Marco Silva.
Silva controls with aplomb I have to say.
More injury bother in the Hull back line. Andrea Ranocchia is again in the wars after taking a clout from former Tiger Robert Snodgrass.
A bruising afternoon for the Italian but he'll be back on in a moment or two.
The second half begins.
A half-time change for the hosts and it's Curtis Davies who's been hauled off.
A change to a four-man defence is the order of the day and it's Poland winger Kamil Grosicki who comes on.
A half that very much sums up why Hull are where they are in the table.
A patched-up West Ham side on a poor run of form have come here and really not been troubled, with Manuel Lanzini and Andy Carroll causing the hosts all kinds of bother.
Carroll's goal was totally avoidable from a Hull perspective while the hosts have also been rushed and aimless in attack.
This is a big half-time team talk coming up for Marco Silva.
Andy Carroll must be an absolute nightmare to play against.
He just went thundering into Andrea Ranocchia as they challenged for the ball and ultimately forced the Hull man to boot the ball out for a corner 30 yards from goal.
The Italian looks perplexed by that little sequence of play.
Harry Maguire limping for Hull now.
Michael Dawson will surely be needed at some point today.
Two of Hull's centre-backs have picked up knocks and the third, Curtis Davies, was at fault for the goal. Dawson's presence back there would not go amiss.
It's been a scrappy old half for the most part. The best player on the park is definitely Manuel Lanzini. When he's in possession things just looks a little bit calmer out there. He'll always pick a pass and always drift into space.
West Ham captain Andy Carroll is down needing treatment after taking a bit of a whack as the visitors cleared a Hull free-kick.
It was partly a hit from his goalkeeper and partly a heavy landing.
Think he's OK though.
Better from Hull. Lazar Markovic leads a quick counter and picks out Oumar Niasse down the right. The ball eventually breaks to Amed Elmohamady who sees his drilled effort charged down.
Top marks Elidin Jakupovic. The Hull goalkeeper has to go full stretch to keep out a superb low strike by Manuel Lanzini, who cut inside from the left and fired in a powerful effort with his right foot.
West Ham's defence creaking under pressure from Hull there but it was all very scrappy from the Tigers.
Lazar Markovic might have taken a shot on the initial attack but elected to take the ball wide from where Ahmed Elmohamady fired over a cross that West Ham scrambled clear.
It's very untidy from Hull going forward. They need much more composure.
Former West Brom striker on Final Score
Carroll has been a big player for West Ham today. Again, poor defending from Hull here.
It's a difficult finish for Carroll - he had to bring it down on his chest and control it well but Curtis Davies shouldn't get caught under the ball like that - he had plenty of time to see it and act on it.
A very untidy moment for West Ham goalkeeper Darren Randolph, who tries to take the ball around Lazar Markovic but his touch is too heavy and Abel Hernandez is there to pressure him.
Randolph actually went in pretty heavily on Hernandez as he cleared the danger but wasn't pulled up by the referee.
More trouble for Hull here with Italian defender Andrea Ranocchia down and in need of treatment after appearing to injure his ankle in a standing challenge with Manuel Lanzini.
Michael Dawson is available off the bench but this is not what Hull need.
Not a moment Hull captain Curtis Davies will want to see again.
A simple, lofted ball into the area by Aaron Cresswell somehow evades the Hull centre-back allowing captain-for-the-day Andy Carroll to bring the ball down on his chest and apply a smart finish beyond Eldin Jakupovic.
Too easy for the big striker, and that's his 50th career Premier League goal.
Almost the moment all Hull fans have been dreading as the ball is crossed to the far post for the waiting Robert Snodgrass but his header lacks power and Eldin Jakupovic saves. The Scotland man looked to have strayed offside there so it would have been double frustration for the hosts had that hit the net.
Ahmed Elmohamady is back in the Hull line-up today and forces a corner when his cross from the right is blocked. West Ham clear but when it's fired in again by Alfred N'Diaye Jose Fonte has to slide in to force another corner.
