Derby have men forward in a promising position but a Chris Martin backheel is misplaced and they give away possession.

Can there be a late twist? Hull want to wind down the clock. Derby have a little over five minutes plus stoppage time to make it 3-3 on aggregate and force extra-time.

Time for a hero? Darren Bent is on.

He replaces Derby's opening goal scorer, Johnny Russell.

Derby will be very conscious that time is starting to run out.

It's been a brave, valiant effort - but have they got enough about them to complete a remarkable comeback?

The delivery is whipped in dangerously but Derby head the ball away from danger. Ahmed Elmohamady then does well to win another Hull corner. This will really please the hosts. They have the ball where they want it.

This time it's aimed for Curtis Davies but he heads over.

Derby win back possession and look to pick out Chris Martin with a very long ball upfield but Eldin Jakupovic gathers in his area.

Straight down the other end, Hull win a corner themselves.

Hull enjoy their longest passage of play in Derby's half for the entire game but it ends when Ahmed Almohamady runs then ball out for a goal kick to the visitors.

But they come forward again and this time win a corner. Can they finish off this tie?

Tom Ince shoots from outside the area but it's way, way off target. A waste.

Derby are still searching for the leveller in the tie. Hull are sitting back, dangerously.

Derby are almost in on goal with Tom Ince but, as he cuts inside, Michael Dawson cuts in to clear for a corner.

Then Eldin Jakupovic is called into action for pretty much the first time of the entire tie, and he does excellently to save a curling Chris Martin shot.

The keeper can't have seen that until very late because of a crowd of players.

Derby keep coming and keep coming but eventually the ball runs out for a goal kick.

A lengthy period of Derby pressure ends with Will Hughes shooting well wide from outside area. Hull can regroup.

Derby make a few attempts to get in behind the Hull back line but the hosts hold strong.

They've got some experienced defenders back there, have the hosts - and they'll need to draw on all their years in football in these final 22 minutes.

How often have we been here before in the Championship play-offs: one goal in it, both sides going for it, 25 minutes to go? These matches deliver year after year.

You have to love the play-offs! This is yet another belter, and the tension is just crazy.

Mohamed Diame strides towards the Derby penalty area and tries a left-footed shot but he drags it low and wide. That lifted the home crowd though, that's for sure.

Hull try to break and get the ball up to Robert Snodgrass, who could be through on goal past the last man, but Jason Shackell makes a vital intervention.

Andreas Weimann can't continue and he goes off, to be replaced by Tom Ince.

Derby come forward again but Jeff Hendrick's ball into the box is too heavy and goes long for a goal kick.

Meanwhile, Derby's Andreas Weimann is limping awkwardly. He looks hurt.

Hull's top scorer Abel Hernandez tries his luck with a volley on the turn from a relatively tight angle but it goes wide across goal.

Derby's Jason Shackell trips Moses Odubajo and he goes in the book.

One Hull goal would surely take the sting out of this tie.

A Robert Snodgrass free-kick for Hull strikes the wall. That was too low to threaten the Derby goal.

Oh boy, what Steve Bruce would give for a home goal now. The tension around the KCom Stadium is clear for all to see.
