British promoter Frank Warren disclosed details of the contract between Oleksandr Usyk (22-0, 14 KOs) and Tyson Fury (34-1-1, 24 KOs), who will face each other in a rematch on December 21 in Saudi Arabia.
"It’s in the contract. Whatever happens, it will be so if Tyson wins. Provided that neither of them retires," Warren stated.
In their first encounter in May, Usyk won by split decision.
