Heavyweight Champion of the World Tyson Fury last night sensationally claimed he'd retire after he fights Wladimir Klitschko - win or lose.

The outspoken Fury, speaking to IFL TV's Kugan Cassius at our bumper Copper Box show last night, made the bold claim after watching his cousin and stablemate Hughie win over tricky Fred Kassi.

"I've got two and a half stone to get off and I want to get on it," said Fury. "It's going to be my last fight, I think. Sh** or bust. All or nothing. It's going to be my last fight win, lose or draw. I just can't be f***ed with it. I'm so sick of it. I've got no motivation to carry it on," Fury claimed.

Hughie outpointed Kassi to claim his first professional title in the Vacant WBO Intercontinental Heavyweight championship at the Copper Box Arena. Fury, cousin of World Heavyweight Champion Tyson, looked in complete control of the bout before the referee stopped the contest in the sixth round after a cut to Fury’s left eye caused by an accidental clash of heads left him unable to continue.

New Orleans-based Kassi attempted to make life difficult for Fury by switching between orthodox and southpaw but 21 year-old Fury comfortably dealt with everything thrown his way. A low key third round saw Fury move from second gear into third, still dictating the pace of a tactical bout.

A nasty gash on undefeated Fury’s left eye began to open up after an accidental clash of heads in the sixth round. With blood streaming down the heavyweight prospect’s face an early stoppage loomed. The referee decided to end the title contest in the eighth round after taking a close look at the damaged eye.

With Fury unable to continue it went to the judges’ score cards. All three judges scored the fight in Fury’s favour (69-66, 70-64, 69-65) and the mancunian heavyweight destroyer took his record to 20-0.
