Heavyweight challenger Tyson Fury will be taking on by far his biggest challenge against Wladimir Klitschko on Oct. 24 in Germany, and the Englishman is now suggesting that he will retire from the sport should he fail to KO the aging champion.

“(Klitschko is) getting knocked out, end of. He’s never fought anyone like me – he’s never seen or been in with someone who is 6-feet-9 and who can move all round the ring,” said Fury to Sky Sports News. “He’s only fought big men who can’t move or small guys who he can hold off with his claw and grab style.

“If I can’t beat and knock out a 40-year-old man, who has had his career and been a great champion because there’s been nobody of any note to fight, then I must be useless and should be banned from boxing. And I won’t be boxing on because it will mean I can’t achieve my goals.”

Fury, 27 last month, goes into battle with a perfect record of 24 wins, including 18 inside the distance.

Klitschko (64-3, 53 KOs), meanwhile, just hopes his mouthy challenger can live up to all his pre-fight trash chat.

“I promise everyone an exciting evening and I hope that Tyson Fury is also going to walk his big talk,” said the Ukrainian, who is actually 39, on www.skysports.com. “I will be ready when October 24 arrives, hopefully Tyson will be too.”

Sky Sports confirmed Friday that Klitschko-Fury on Oct. 24 will go out via its pay-per-view service, alongside Kell Brook’s IBF welterweight defense earlier the same evening in Sheffield, England. Local favorite Brook (35-0, 24 knockouts) faces Diego Chaves (23-2-1, 19 KOs) at the Motorpoint Arena.

It means more than six hours of live boxing for the British TV audience – with Manchester man Fury’s bid to dethrone all-conquering Klitschko, the longstanding RING, WBA, WBO and IBF holder, undoubtedly the blockbuster attraction.
