I think we might be getting to the stage where Derek is going to have to go for it as I have Usyk pulling away.

Into the second half.

Press the play button at the top to listen along.

Usyk is looking good in this round, up on his toes, a rapid left, a rapid right, both land and he's out of range before Chisora can respond.

Usyk boxing beautifully.

Another Chisora looping right, but Usyk sees it coming, dances out of the distance and it ends with Chisora making a rather ugly-looking miss. Chisora clearly thinks he needs to knock out his opponent and is preparing to put everything at risk to try to do it.

Derek Chisora’s corner after round five: "Breathe as deep as you can. The only reason he caught you with a couple of shots is you’re throwing singles and standing still."

At the end of the fifth Derek Chisora is breathing heavily. Has he punched himself out?

However, if he lands with one of those massive shots that he is throwing, then that could be game over. That's the beauty of heavyweight boxing.

Usyk, still looking fresh, still moving nicely. Five gone.

Chisora dives in and connects with a body punch but Usyk, who won the cruiserweight world title in only 10 fights, is making the Briton miss a lot more than he would like.

Another lunge, this time looking for a big right for Chisora, but it is an energy-sapping failed attempt.

British heavyweight Dillian Whyte on BBC Radio 5 live: "I think Derek needs to believe in his boxing a bit more. Stop head hunting and target the body more."

Chisora's gameplan has definitely been to finish his opponent in the early stages, but how much will he have drained himself in an attempt to do so?

Usyk picks off Chisora with a couple of jabs.

Usyk later hits the canvas, but it was a slip, not a punch and no count took place.

Chisora half-catches Usyk with another swinging overhand right - that's what he has had the most success with so far, but at no stage has Usyk been in trouble yet.

British heavyweight Dillian Whyte on BBC Radio 5 live: "Chisora is on the red line. He’s not thinking. Sometimes you need to step back, reset and go again. David Haye needs to get hold of him."

There was a lovely short, sharp left from Usyk in that third. Not a shot Chisora will be able to take too much of that. But he did take that one.

Towards the end of the third, Usyk has Chisora pinned in a corner, but a swinging overhand right from the Briton forces himself out of trouble.

After a bit of wrestling on the ropes, referee Phil Edwards has a word with both men.

It's a fearless, all-out attack from Chisora. He's not going to leave anything in the tank.

Usyk tries to bounce on his toes and keep the bigger man at bay. A swinging left and a swinging right from Chisora both miss and he spins around.

British heavyweight Dillian Whyte on BBC Radio 5 live: "Usyk is getting a bit better, setting Derek up a bit. I’d say Derek has two rounds."
