Tyson Fury repeatedly called rival Oleksandr Usyk a “little rat b*****d” and a “little s**thouse” after their fight fell through.

WBC champion Tyson Fury has broken his silence and dropped an astonishing X-rated callout of unified title holder Oleksandr Usyk after their mega-fight collapsed this week.

Fury, who hasn’t fought since his trilogy fight against fellow Brit Derek Chisora last December, appeared on course to face Usyk at Wembley Stadium on 29th April.

However, their hotly anticipated undisputed heavyweight showdown fell through after Usyk’s promoter, Alex Krassyuk, slammed the Fury camp over their demands in the negotiations.

Fury initially called on Usyk to agree to a 70-30 purse split, with the undefeated heavyweight Ukrainian calling his bluff and accepting the audacious offer.

The ‘Gypsy King’ then called on Usyk to withdraw the rematch clause from the negotiations, which appeared to be the final straw in the back-and-forth talks.

The 34-year-old Brit superstar took to his Instagram Stories (watch it in the video player above) on Thursday and launched a war of words with Usyk.

WBC kingpin Fury can be heard repeatedly calling the 36-year-old champ a “little s**thouse” and a “little s**tbag,” with Usyk branded a “little coward.”

Speaking in the Instagram clip, Fury said: “Usyk, you little s**thouse, you proper little s**tbag, bogeyed, gappy teeth, ugly little rat b*****d.

“You little slimy f****r. Tried all week to get out of it, begging for a rematch like a little girl. You got your rematch and you didn’t even want to fight at that.

“You little s**thouse pussy. Always know pussy that you know you was never man enough to tangle with the ‘Gypsy King’ ever in your life, you little s**thouse.

“You little 14-stone coward. You little s**tbag, you rat little b*****d, and your full team know it as well.

“I have all the lawyers and got the full information, you little ugly b*****d. Keep running.

“[…] Always know that you or anybody else like you could ever tangle with the ‘Gypsy King,’ you s**thouse little coward.”

Fury’s co-promoter Frank Warren believes that the super-fight between the pair is now a “dead duck,” despite desperately trying to save the clash in last-ditch talks.

“They said the fight must take place before 29th April and if it goes later they want different splits,” he said.

“The reason they did that was they didn’t think Tyson would be ready for the 29th and suddenly Tyson was ready for it.

“He has been in training camp for two and a half weeks, got trainers in from America and they looked for a way to get out.”
