Oleksandr Uysk's next opponent is CONFIRMED 🚨🥊 Frank Warren has revealed the winner of Joseph Parker vs Fabio Wardley at the O2 on Saturday evening will face Oleksandr Usyk next. Victory for either fighter will secure mandatory challenger status for the WBO title currently held by Usyk, who also reigns as the unified and Ring Magazine heavyweight champion. Under the governing bodies' system, the WBO is next in line to call a mandatory defence. That order was originally issued in July, but plans were pushed back following Usyk's back injury. #oleksandrusyk #usyk #frankwarren #boxing #long
