Deontay Wilder claims Tyson Fury won’t be able to sleep because he is so nervous about their rematch.

Wilder feels Fury is worried ahead of their February 22 showdown at the MGM Grand Garden Arena in Las Vegas because he knows he lost their controversial draw in December 2018.

Wilder twice floored Fury, despite his claims that he had a bust right hand, and says the traveller will be haunted by the fact he gave him concussion.

The unbeaten WBC heavyweight king said: “I feel he’s nervous deep down in his heart. I feel he is very, very nervous from the first time what happened.

“When you knock someone down and give them a concussion, you don’t forget that. You never forget who did it and how they do it.

“When you’re going in the ring with them for a second time, to relive that moment all over again, then it has to be stressful.

“You definitely can’t sleep at night and I understand why he is changing up a lot of things in his team.”

Wilder, 34, who is 42-0-1, claims Fury’s decision to replace Ben Davison with SugarHill Steward as his trainer shows he knows he lost the first fight.

The Bronze Bomber says Fury would not have made such sweeping changes if he genuinely believed he had won.

“For me, I just think that’s nervous energy from the first fight,” he said. “He can go and say he beat me by a wide margin, but he doesn’t believe that.

“That’s why he’s changed up a lot of things. If you really believe that, you would not change so much.

“I don’t think he’s confident in his head because he understands how I left him. I gave that man a concussion.

“It could easily happen again because the head is not meant to be hit, especially by the power of someone like Deontay Wilder.”
