Frank Warren claims Tyson Fury told his brother Tommy that he would “deny” him if he lost to Jake Paul, just before taking out Deontay Wilder.
The legendary promoter, who represents the two siblings, has been trying to organize a fight between the relative novices since August.
Paul called Fury in March, the couple having since traded verbal punches on social media, only to come face to face in Cleveland.
The YouTube star beat Tyron Woodley in his hometown on a night when Fury was on the undercard against Paul’s training partner Anthony Taylor.
With Warren confirming that an announcement could be made “in the next few days,” the head of Queensberry Promotions has revealed how much the 22-year-old has received from his family.
Just before “The Gypsy King” knocked out Deontay Wilder to retain his WBC heavyweight title, he and his brothers threatened to “deny” the youngster if he lost to Paul.
“Well, it’s a big bet, but it’s a very lucrative bet,” Warren told talkSPORT.
“He’s extremely well paid and I’m not going to stop myself from getting some serious, life-changing money.
“He’s paid a lot of money in a fight that I believe he’s winning.”
He added: “He’s going to have to win the fight or the family will deny him!”
“You should have heard them in the locker room, right before Wilder’s fight, I was there when they told him.
“Look, there’s going to be a lot of pressure on Tommy and he’s going to be in the other guy’s backyard.
“But he’s from the combat stock and I think he’s been beaten.”
Fury has previously said that Tommy “should change his name” if he loses to Paul, while Uncle Peter Fury has suggested he “get on dancing” if he can’t take the win.
