Fury and Wilder faced off at a news conference just days from their rematch at the MGM Grand in Las Vegas, and they shoved each other before being separated.
Fury, who drew with Wilder in their previous bout in December 2018, believes his opponent is showing signs of nerves.

“Wilder is very nervous. I can see his jumper going in and out from the big heart beat pounding out of his chest,” Fury said.
“He’s terrified. He’s nervous as hell. He doesn’t know what to expect, and he’s getting knocked out.”
Wilder laughed off Fury’s suggestion ahead of Saturday’s showdown, where he will defend his WBC title.
“When I knock you out, go do stand-up comedy. You’ve got a career there,” Wilder told Fury. “You’ve got pillows for fists and that’s why I kept running through you.”
