Luke Campbell vs Yvan Mendy

Joshua's fellow London 2012 Olympic gold medallist Luke Campbell takes on French fighter Yvan Mendy in a repeat of their 2015 encounter.

Campbell, who was then undefeated, succumbed to Mendy in a contentious points decision at the O2, but the Hull-born fighter is confident of exacting revenge to earn a shot at the WBC lightweight title.

"I'm excited to go out there and continue showing better performances and keep on improving," said Campbell ahead of Saturday.

"I don't really look back at that night, I don't think I've even watched the fight back. "The things I was doing that night wasn't what I normally do, It was a lesson learnt. I'm moving forward with that now and can't wait to put it right."

Matty Askin vs Lawrence Okolie

Saturday night sees another former Team GB boxer take to the ring in the form of Hackney-born Lawrence Okolie.

Okolie, who is managed by Anthony Joshua, meets Barnsley's Matty Askin for the British cruiserweight title.

2016 Olympic silver medallist Okolie has impressed in his nine fights since turning professional but has only gone beyond round six once in his short career.

Tony Bellew has backed Okolie to wrestle the British cruiserweight title away from Askin, calling 'The Sauce' a world champion in waiting.

"Okolie is the dangerman in the division, he really is. Very dangerous on the front foot, very long, very rangy," wrote Bellew in his column for Sky Sports.

"He's a big, dangerous dude, and I'm enjoying watching him, I really am. I'm a fan and a supporter of his, and he's a breath of fresh air for the British cruiserweight division."

Sergey Kuzmin vs David Price

It could be last chance saloon for David Price as he attempts to resuscitate his career after a devastating knockout defeat at the hands of Alexander Povetkin in March.

The Liverpudlian heavyweight is up against a Russia once again, this time in the form of Sergey Kuzmin.

Kuzmin once beat British Olympian Joe Joyce as an amateur and holds a 12-fight undefeated record as a professional.

But Price is adamant he has the ability to inflict Kuzmin's first loss as a pro.

"The difference with this fight is that for the Povetkin fight, I had doubts going into it, whether I would be able to compete with Povetkin, because my last fight was a six-round fight," said Price.

"This time, I know I'm better than Kuzmin. I know I'm a better fighter than him, so I'm going to be getting in there with that assertiveness, and confidence to go from the word go."
