Oleksandr Usyk would be willing to fight Tyson Fury in the streets after the pair's undisputed fight fell through.
Fury was in talks to face Usyk in a deal which would have seen Anthony Joshua and Dillian Whyte step aside from their planned fights with the heavyweight champions.
But talks broke down and Fury opted to face mandatory challenger Whyte instead, with Usyk expected to fulfil his rematch against Joshua.
