Why is Usyk challenging Joshua?
Originally Joshua was preparing to take on Tyson Fury, in a highly competitive and explosive ultimate World Championship fight in Saudi Arabia.
In mid-April, Fury’s promoter Eddie Hearn confirmed the fight was set to go ahead and both were in preparation for the event.
However, Fury was ordered by an independent adjudicator to fight American Deontay Wilder, who argued he was legally bound to a re-match of their February 2020 bout. Fury won the fight, making him the two-time world heavyweight champion.
Fury and Wilder will now fight in Las Vegas on 9 October, but Joshua was unimpressed by the cancellation of his meeting with Fury.
When the Joshua v Fury fight failed to materialise, Joshua called Fury "a fraud".
Now, he will face Usyk, who is the former undisputed world cruiserweight champion with 18 wins in 18 fights.
