Tyson Fury vs Oleksandr Usyk bout on the verge of being cancelled

Loquacious British boxer Tyson Fury’s undisputed clash with Oleksandr Usyk is "not far off" collapsing, according to promoter Frank Warren.

The Gypsy King, 34, has been in talks with the Ukrainian's team ever since he successfully defended his WBC crown against Derek Chisora in December.

A clash in Saudi Arabia appeared to be the most likely location for the bout - which would see all four world heavyweight titles on the line.

But a failure to secure a site fee in the Middle East has left them looking at Wembley on April 29.

However, Fury's promoter Warren has now cast doubts about the fight taking place at all.

Speaking to iFL TV, he said: "We're getting to a situation where one way or another we're going to have to make a decision.

"And we're not far off that."

Fury and Usyk are both undefeated as professionals and widely regarded as the two best heavyweights in the world.

Since moving up from cruiserweight, Usyk has beaten Derek Chisora and Anthony Joshua twice.

But before that, Fury ended Wladimir Klitschko's reign with a superb win in 2015 and then left the sport for three years due to mental health issues.

He returned in 2018 and has gone on to beat Deontay Wilder on two occasions, as well as Dillian Whyte and Chisora.

If a Fury-Usyk fight does not materialise, an all-British dust-up with Joe Joyce could be next up for the WBC champion.

Last month, Warren hinted at a summer clash between his two men Fury and Joyce.

Joyce is set to face Chinese heavyweight Zhilei Zhang at the Copper Box Arena on April 15 as he awaits a world title shot.

But he could be thrown into a Fury clash instead should the opportunity arise.

Speaking in a recent column, Warren said: "Our big hope, of course, is that the Juggernaut [Joyce] remains on a collision course with Tyson Fury and a big summer date at Wembley.

"That is the plan if Tyson takes all the titles from Oleksandr Usyk and Joe does the business on April 15 in Stratford,"
