Usyk's opponent, former WBC champion Tyson Fury (34-1-1, 24 KOs), has been advised to rest for one week.
The rematch between Usyk and Fury was initially planned for October. However, the head of the General Entertainment Authority of Saudi Arabia, Turki Alalshikh, announced that the fight is now scheduled for December 21 in Riyadh, Saudi Arabia.
On the night of May 19, Oleksandr Usyk defeated Tyson Fury by split decision to become the undisputed heavyweight champion. Usyk is the first undisputed champion in this division since November 13, 1999, when Lennox Lewis defeated Evander Holyfield in a rematch.
