New Zealander Joseph Parker will fight the undisputed heavyweight world champion winner of the Oleksandr Usyk v Daniel Dubois fight in London in July, promoter Frank Warren said on Tuesday.

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.

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.
