Oleksandr Usyk's promoter Alex Krassyuk has said a much-anticipated fight with Tyson Fury for all four of the world heavyweight titles is "in the making".

Usyk was a split-decision victor in his rematch against Anthony Joshua on Saturday in Jeddah, retaining the WBA, IBF and WBO belts that he took off the same opponent at the Tottenham Hotspur Stadium last year.

It means that the Ukrainian would now just need the WBC belt to make him only the second fighter in the four-belt era behind Claressa Shields to become undisputed in two different weight classes, having already held all four titles in the cruiserweight division.

That WBC belt belongs to Fury, who has not been in the ring since April when he defended his strap by stopping Dillian Whyte with a brutal uppercut in the sixth round at Wembley.

Fury has since claimed to be retired, but it appears that he could be tempted back into the ring to face Usyk and crown an undisputed champion in the heavyweight division, after telling his Instagram followers he would "annihilate" both Usyk and Joshua following the conclusion of their rematch.

And Usyk's promoter Krassyuk is confident the fight between the two undefeated titleholders will happen, telling Sky Sports on Tuesday: "It's in the making."

Speaking on Monday, meanwhile, Fury's co-promoter Frank Warren also indicated he is confident of the Briton getting in the ring with Usyk.

"[Fury] and Usyk would be a really good fight," Warren told BBC Radio 5 Live. "It's a fight that I think will be made because both teams would like to see that happen.

"Usyk said after the fight that it's the only fight he's interested in, and it's certainly the same case with Tyson. It's just a matter of where it will generate the most income because it's a unique fight, a historic fight."
