An agreement has been reached for a unification fight for the world heavyweight boxing belts between the British Tyson Fury and the Ukrainian Oleksandr Usyk, on a date to be determined, promoter Frank Warren announced on Friday.

The “biggest event of the century in boxing”, according to Warren, will be held in Riyadh, Saudi Arabia, between Fury, holder of the WBC heavyweight belt, and Usyk who barely retained the WBA, IBF and WBO titles against the British hopeful Daniel Dubois at the end of August.
