Oleksandr Usyk has set a firm deadline for his undisputed heavyweight title clash with Tyson Fury, with the Ukrainian's manager declaring it must happen by March 4.
The heavyweight duo hold all of the belts in their division, with Fury having the WBC title while Usyk is the WBA super, WBO and IBF champion. He also holds The Ring Magazine 's ceremonial title that indicates the No.1 heavyweight in the world, as well as the considerably less prestigious IBO world title.
There hasn't been an undisputed champion at heavyweight since the WBO belt began to be recognised as a major title and the four-belt era began. Lennox Lewis was the last to be undisputed in the division back at the turn of the millennium, and nobody has been able to win them all since.
