Regardless of what happens in his rematch with IBF heavyweight champion Daniel Dubois on Saturday, WBA, WBC and WBO champion Oleksandr Usyk already has a Hall of Fame resume. Beating Dubois would make Usyk -- a former undisputed cruiserweight champion -- undisputed heavyweight champion for the second time in his career.

When Usyk rematches Dubois for boxing's undisputed heavyweight championship on Saturday, he does so against a different fighter from the one he disciplined two years ago.

Oleksandr Usyk's WBC, WBO, IBO, and The Ring heavyweight titles will be unified with Daniel Dubois' IBF heavyweight in a clash at Wembley Stadium in London. Will Usyk record his second straight victory over Dubois? Or will the home advantage of a partisan UK crowd carry Dubois to an upset victory?
