TYSON FURY blasted Oleksandr Uzyk for going 'life or death' with Derek Chisora, and called Anthony Joshua a 'cross-fit bum.
Fury, 33, was in negotiations to face Usyk (35), in Saudi Arabia for undisputed heavyweight title.
Tyson Fury attacked Oleksandr Usyk's decision to go 'life or death' with Derek Chisora
AJ lost to the Ukrainian in September and failed to reach a compromise to forfeit his contract rematch as part of a financial package.
Joshua, 32, will instead rematch Usyk, while Fury will defend the WBC title against Dillian Whyte (33).
The National was told by him: "You can only take what you can fight at the moment."
"I have Dillian Whyte and Usyk next. I'm going absolutely to set about rotten.
"The middleweight. Send him packing. Send him back to middleweight. That's all I have to do.
"AJ is a huge old bodybuilder. He's not worth a carrot. I don't want you to hear about how great Usyk is.

"And then, he fought with a bodybuilder who isn't even a boxer and had both a life- and death.
"Until he faces a real fighter man, you can't call him champion." All roads lead me to my goal; I am the 'Gypsy King.
"If he could beat me, I would say he is a good man." However, if he doesn't beat me, I'll still consider him useless."
Further details will be provided on the first ever heavyweight unification of all four belts.
Fury believes that Usyk will be the next opponent, and he is likely to win.
He stated that Usyk would beat him in the rematch. Yet again. Because AJ is a bum, he cannot fight.
He's been exposed. He is a cross-fit bum. That's all I have to say.
