Anthony Joshua accepts his career is on the line when he faces Oleksandr Usyk in today's world heavyweight title rematch in Jeddah.

A fight delayed by Russia's invasion of Usyk's native Ukraine will see Joshua attempt to reclaim the WBA, IBF and WBO belts he lost to his rival on a passive night at Tottenham Hotspur Stadium almost a year ago.
