John Fury has issued a chilling warning to Deontay Wilder ahead of his son Tyson Fury's delayed trilogy bout in October.
Fury vs Wilder 3 was scheduled for July 24, but a positive Covid-19 test put paid to that date and the new fight will now take place on October 9.
And while Wilder was publicly vocal about doing some serious damage to Fury at the T-Mobile Arena, Fury's camp have hit back ahead of the postponed fight.
"My mind is very violent," Wilder said in June. "We built a whole facility to commit a legal homicide and that's just what it is, my mind is very violent at this time."
Now though Fury senior has shockingly claimed Wilder's clash with the 'Gypsy King' could "cost him his career and his life".
Speaking to Boxing Social, Fury senior claimed Wilder's camp chose to fight Fury because they fancied their chances against the Brit.
'If he's not dead, he'll be an invalid'
Fury said: "Like Tyson got cherry-picked with Deontay Wilder twice.
"Because if they never saw Tyson's eye hanging off against Otto Wallin, a terrible performance, they wouldn't have wanted the second fight.
"But they saw the Otto Wallin fight and thought, 'Yup, Wilder can't lose. Wilder will chin him.'
"They cherry-picked him the first time thinking, 'He's been out of the ring for years, he's been abusing himself. We can't lose.'
"But every time Tyson, when he's in that ring, he changes his full job."
Fury senior believes Wilder's camp have got it wrong twice and they have got it wrong again - a mistake, which he suggests could leave Wilder permanently injured, or even dead.
"'He can look terrible in a training camp, but when he gets in that ring, he's a different man, different animal. And they got it wrong twice.
"And they'll get it wrong the third time. But the third time will cost him his career and his life, probably.
"If he's not dead, he'll be an invalid, which is a silly man. But if they want to sell their soul and put their life on the line for money, which I'm sure they will, get on with it."
AJ will 'walk straight through Usyk'
Meanwhile, The father of the WBC heavyweight champion also believes Anthony Joshua will be too big and strong for mandatory challenger Oleksandr Usyk when they collide in September.
The pair will clash at Tottenham Hotspur Stadium on September 25 with Joshua's WBA, WBO, IBF and IBO heavyweight titles on the line.
Usyk, who defeated heavyweight Derek Chisora by unanimous decision in October 2020, is stepping up from cruiserweight.
The Ukrainian, 34, unified the entire cruiserweight division in 2018, but Fury believes he will struggle against the size and power of Joshua.
"Usyk is good. He's a world-class cruiserweight, [he's] proved it. But AJ is a big dude and he's got a good array of boxing skills and he's a big strong man. And I just think he's all around too good for Usyk," John Fury added.
"Usyk won't be able to hit hard enough to bother him because he's too small. He'll walk straight through. I think AJ will stop him quicker than anybody else. I think AJ will walk straight through him. I do.
"One's a cruiserweight, one's bulking up. And if he bulks up to try and meet him head-on, forget about it. That's why there's weight classes, ain't they. A good biggun (sic) will always beat a good littlun (sic). And AJ is a good biggun (sic)."
