Tyson Fury and Oleksandr Usyk will meet for the chance to become the first undisputed heavyweight champion in the four-belt era Saturday night in Riyadh, Saudi Arabia (ESPN+ pay-per-view, noon ET).

Fury (34-0-1, 24 KOs), is the WBC and lineal champion. Usyk (21-0, 14 KOs) has the WBA, IBF and WBO belts. The last time boxing had an undisputed heavyweight champion was in 2000 (Lennox Lewis, three-belt era).

Ahead of Saturday’s fight, Fury seems to be in much better shape than he was when he had to pick himself up off the canvas in October in a split-decision victory against former UFC champion Francis Ngannou.

“It’s the fight of the century,” Fury told ESPN on Wednesday. “[An undisputed heavyweight championship fight] has never happened this century before, and we’re looking forward to putting on a fantastic show.”

The fight was scheduled for February before Fury suffered a bad cut over his right eye during a sparring session. Usyk last fought in August, a ninth-round KO win over Daniel Dubois in a fight where he was seemingly dropped in Round 5 by a body shot, but referee Luis Pabon ruled it a low blow.

“Saturday is a special day because I will have the opportunity to become undisputed for a second time,” Usyk said. “It’s great. It’s very good for me. It’s very important for my country. I like that.”
