The two men are exhausted. Where are they finding the energy to keep throwing punches?

This is a fight to remember.

Bellew dives straight in looking to finish this one. It's a slugfest now, both boxers trying to find that knockout blow.

But Haye's limping and that means Bellew can pick him off at will, left, right, he swings in as Haye desperately tries to hold on.

Haye's ankle is broken or twisted. He's got rubbish boots - there's no support!

This is Bellew's chance, Haye is down once, gets back to his feet but another Bellew hook sends him crashing down again.

Haye's on the ropes - and he's down for a third time! He struggles to get up, it's all Bellew, brutal from the Bomber.

Haye is in serious trouble here.

Into the sixth then, both fighters looking for that gap and it's Haye who attempts to strike first with a blow that's brushed of by Bellew.

Bellew catches the opponent with a right, slips but then counters Bellew and has the Bomber on the deck.

But Haye's knee looks to have gone, he's limping round the ring trying to land the winner while he can still walk.

There's a look of menace and confidence about David Haye. He has a look of experience. You can see him thinking 'it's just a matter of time'. 

I am impressed with Haye.

David Haye said he doesn't like to eat too much on the day of a fight, so he goes in there hungry for a win - well he has probably eaten more blows from Bellew than he would have expected. But he has settled down and is enjoying some success in this round.

Haye looks to have settled into this a little more now, and connects again with a right before backing Bellew up into the corner.

A couple of big shots as Bellew almost got tangled in the ropes. The Bomber survives, but Haye will take that round.

Well this is further than many said it would go.

Has Bellew shrugged off that earlier blow? He's the one to go on the approach this time as Haye throws a jab to the body.

Tony Bellew took two big shots from Haye but he took them well because he was moving away and that's why he didn't get knocked onto the canvas. It was a dominant round for Haye but Bellew withstood it. 

Perhaps the cleanest punches of the fight so far in that round. An overhand right followed by a brutal left hook. Bellew took them well though, still steady on his feet and throwing back. Haye's round for sure.

And there's the big shot from Haye. A couple of jabs before landing a hook on Bellew's cheek - it looked like he felt that.

Bellew dives in, but Haye bides his time and looks for another flurry of big shots.

I think that hook rattled Bellew, he doesn't look quite as comfortable as he did at the beginning of this round.

This is defying the forecast because they said Haye would tire first and that Haye would land more heavily, but Bellew has landed just as heavily and Haye is still looking sharp.

The longer this goes on the more Bellew will fancy his chances.

No doubt Haye realises that and he's the one who goes hunting again, but the big punches just aren't connecting at the minute.

Bellew's defensive approach is working so far.

Bellew is oozing confidence. Not many expected the fight to start this way. Neither fighter is connecting with a jab, both just want that one punch knockout. What a scrap.

Bellew came out flying in the first, but he's eased off a little and Haye takes his chance to swing a left hook at his opponent.

That was huge, but Bellew ducks out of it and then sidesteps his way across the ropes out of Haye's reach.

A little afters after the bell there? The referee splits that up.

Bellew is staying out of harm's reach and doing exactly what he needs to do. This is so tense and so well poised. It's better than we expected.

It's fascinating this one.

Haye again on the hunt early on. The majority backed him to knock out Bellew in the early rounds, but he's not been able to connect meaningfully so far.

Haye takes the centre of the ring and mixes it up with a low shot before a left-hand jab into Bellew's guard.

Incredible round again, a closer one and better for Haye, although Bellew caught him at he end.

Haye is trying too hard and looking for the knockout punch. He's going forward and keeps on missing. He needs Bellew to come forward and walk onto a punch.

Haye's timing is off and he is looking a bit wild. Has all that inactivity taken it's toll on the man from South London?
