That was very close to being stopped there. He saw the ref lurking and said ‘I’m okay’. He said those words.

I thought Derek was winning that round until that uppercut. Both of these guys are exhausted. I don’t see this going 12 rounds.

Eight gruelling rounds of heavyweight boxing and the two are definitely looking tired now.

They both get in close, slamming some heavy hits into each other's bodies.

But another BIG uppercut from Parker sends Chisora scrambling to hold onto the ropes to keep on his feet.

Chisora keeps on going!

Parker’s uppercuts are short but powerful. Chisora took some huge shots but every time you think he’s in trouble he bounces back. The conditioning is incredible from Chisora, but surelyeventuallythese big uppercuts from Parker will pay dividends? Parker is not having to look hard to find the shots with Chisora coming forward in his usual unrelenting fashion.

Dave Coldwell might be onto something here. The body work seems to have slowed Parker down.

Parker slowly taking control of this fight after a big, big round. Will be annoyed he didn't send a hurt Chisora to the canvas but the Brit is hardly an easy man to fell.

Chisora was hurt there and it took him a while to recover. Them uppercuts from Parker are landing pretty clean. Derek’s taken them well, but they’re taking its tool.

Big round for Parker.

Cautious opening minute from Derek. He didn’t do a lot and realised that wasn’t going to work for him. But a good start from Parker, he started aggressive. He didn’t allow Derek to do what he does best.

Joseph Parker, knocked to the canvas inside the first 10 seconds in the first fight, is on the front foot at the start of this one. He's looking for the right hand over the top but Derek Chisora is not giving him anything.

Another chant of "Oh Derek Chisora" reverberates around the arena before the bell goes and the first round is under way!

Derek Chisora is soaking it up as he is announced to the crowd. Huge cheers and roars of approval for the British boxer.

Boos greet New Zealander Joseph Parker's announcement. No change on his facial expression however. In the zone.

Joseph Parker has opted for a sleeveless white tunic for his ring walk. He, like Derek Chisora, looks focused and confident as he looks to repeat his win from back in May.
