Dubois won the interim IBF heavyweight belt by stopping Filip Hrgovic in June, before being elevated to official champion when Oleksandr Usyk vacated the regular belt. The Briton then retained the title in September, with a knockout of compatriot Anthony Joshua at Wembley Stadium. It is unclear what is next for Dubois or the IBF belt.

Modern boxing cards tend to feature just one or two high-level fights, with the rest of the card padded by prospects and fights with lopsided odds. That is not the case with Saturday's event headlined by the rematch between undisputed light heavyweight champion Artur Beterbiev and former champ Dmitry Bivol.

Despite Parker beating Deontay Wilder and Zhilei Zhang in his previous two fights, Johnny Nelson did highlight that a younger Dubois is a different challenge altogether and believes that this could have a huge influence on the result in the Saudi Arabian capital.

Daniel Dubois will not be fighting Joseph Parker this weekend in what would be a huge disappointment for boxing fans.
