Tyson Fury and Oleksandr Usyk face rematching WITHOUT all four belts on the line, reveals promoter Frank Warren

TYSON FURY and Oleksandr Usyk face rematching WITHOUT all four belts on the line, revealed promoter Frank Warren.

The two unbeaten champions are in talks to put every heavyweight title on the line for the first time in history.

But the WBA have already ordered Daniel Dubois, 25, to fight Usyk, while the IBF have done the same for Filip Hrgovic, 30.

The unification will supersede the pair of mandatory challenges, meaning the historic undisputed decider is on track.

Although Hall of Famer Warren admitted if Fury, 34, and Usyk, 35, are to rematch, it could be after relinquishing some of the gold.

He told : “I’m not sure [about the rematch].

"I mean we haven’t got into that, but I probably think there would be [a rematch clause] because, God forbid, one of them gets a cut eye or anything goes wrong - anything can happen in boxing as we know - then there would be.

“The four belts are on the line, and the winner gets them.

"If there is a rematch, I don’t think then the four belts will be on the line for it cause I don’t think the governing bodies will allow it.

"I think they’ll just say ‘right, you’ve got to get on with your mandatories now.'”

Talks between the opposing camps are continuing with the super-fight headed to the Middle East.

And a deadline of March has been imposed as Fury's US promoter Bob Arum provided an update in negotiations.

Arum said: “Both fighters absolutely want it.

“The managers and promoters all want it, so we’re just getting it together and working out where we’re gonna put it on – that’s really the situation.

“It’s gotta go on by March and so we’ve gotta all move quickly so over the next couple of weeks we will or we won’t get it sorted out.

“But everybody wants to do the fight, absolutely want to do it.”
