Johnny Fisher will battle Dave Allen in an all-British heavyweight clash on the undercard for Tyson Fury’s rematch against Oleksandr Usyk.
The former sparring partners will hope to prove their credentials at the expense of the other on one of the biggest cards of the year.

Fisher is set for the toughest challenge of his career as he bids to stretch his unbeaten 12-0 record against his experienced compatriot.
‘The Romford Bull’ knocked out Alen Babic in 36 seconds in July to establish himself as one of Britain’s most exciting new heavyweights.
Allen, who has a record of 23 wins, 6 losses and 2 draws, will relish the opportunity to halt his progress and claim an upset victory.
The 32-year-old has rebounded from losing to Frazer Clarke with two successful outings this year and has sparred headline act Fury before.

Fisher vs Allen: What has been said?
Allen sent a warning to Fisher on talkSPORT’s Fight Night Daily Podcast alongside Gareth A Davies and Spencer Oliver.
He said talkSPORT: “I’m 32 but the thing is like when I boxed David Price, he was finished, he was shot, and I was the young kid coming through, it’s the same thing.
“Johnny Fisher’s smarter than me, like he’s switched on, but he’s a 25-year-old kid who’s never boxed anybody.
“He’s gonna get the shock of his life when he’s trying to hit me. He won’t hit me.
“That’s the thing I boxed Dylan Whyte, boxed Luis Ortiz, Tony Yoka, David Price, Lucas Browne, I sparred Tyson Fury, fought Anthony Joshua [over] 500 rounds [of sparring], I’ve never been on the floor because he cannot hit me.
“Johnny Fisher will get the f****** shock of his life when he starts to try and f****** hit me he will have the shock of his life. Wow, he doesn’t realize.
“I don’t look like a worldbeater – try and f****** do something – God, I cannot wait for him to start trying to take my head off!”
