Frank Warren, co-promoter of WBC heavyweight champion Tyson Fury, has shot down any fears pertaining to a fallout in a unification showdown with IBF, IBO, WBA, WBO champion Oleksandr Usyk.

Last Friday, the WBA was advised, by both teams, that Fury and Usyk had reached an agreement to collide on April 29 in at Wembley Stadium in London.

The WBA was threatening to issue an order which directed Usyk to make a mandatory defense against Daniel Dubois.

On Monday morning, Usyk’s promoter, Alexander Krassyuk, expressed his doubts regarding the fight coming off as planned.

Krassyuk believes Fury will look for any reason to go in another direction - after Fury openly rejected the possibility of a rematch clause.

Warren is not worried and firmly expects the fight to take place.

"Both boxers have agreed to a split and it’ll be on,” Warren said on Monday’s Drive on Talk Sport. “It’s just a matter of contracts but they’re not going to be a problem. I know we’ll get this on. From Tyson’s perspective he’s just putting it out there and putting it on the table, asking why he [Usyk] wants a rematch.

“If he was going to avoid the fight he’d just say, ‘I’m the WBC champion, you get on with your lives, I’ll get on with mine.’ To say that Tyson would avoid any fight; this is the guy that went to Germany to fight Wladimir Klitschko, who at his time was the best heavyweight of his generation, had no problem going over there and actually won the fight. This is the guy that went off to the United States not once but three times to fight the hardest puncher in the heavyweight division.

“Please, the one thing about Tyson is that he’s got balls… just massive balls. There’s no problem with him doing the fight. Secondly, he trains religiously every day… he’s as fit as a butcher’s dog. You’ve only got to look at him, see recent photos of him and you can see how fit he is. He’s ready to go."
