Anthony Joshua wanted a further $5million to skip his rematch with Oleksandr Usyk, promoter Frank Warren has claimed.
Usyk would have faced Tyson Fury for the undisputed world heavyweight championship in the first bout for all the belts since 1999 had a deal been able to be struck.
But for the huge unification bout between Fury and Usyk to take place, both Joshua and Fury's mandatory challenger Dillian Whyte would have needed to be paid step aside money to forego their obligated title shots.
