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.
