Joseph Parker will be rewarded for his patience by facing the winner of Oleksandr Usyk vs Daniel Dubois for undisputed glory, says Frank Warren. Parker, the current WBO interim world champion and mandatory challenger to Usyk, saw a clash with the Ukrainian bruiser snubbed in favour of a rematch with Dubois, which was announced on Sunday.

Dubois, 27, had been set to face former WBO world champion and current interim champion Parker in Saudi Arabia last February but withdrew from the fight due to illness.

Joseph Parker has been the mandatory challenger for the WBO heavyweight title for more than a year. That remains the case, the sanctioning body confirmed on Sunday.
