BBC Sport looks at the numbers behind Daniel Dubois' first meeting with Oleksandr Usyk and what he has been doing to prepare for the rematch on Saturday.

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.

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?
