Usyk still retains the WBA, WBC, and WBO heavyweight belts. He won the WBC strap when he defeated Tyson Fury on points a while back.
The two are scheduled for a rematch in Riyadh, which is set to take place on December 21.
The Ukrainian became the undisputed cruiserweight champion in 2018 after winning the WBC, WBO, IBF, and WBA (Super) titles. He was the first cruiserweight boxer to hold all four major world titles simultaneously. After clearing out the division, Usyk moved up to heavyweight in 2019.
Before turning to pro boxing, Usyk had an impressive amateur career, winning the gold medal in the heavyweight division at the 2011 World Championships and the 2012 Olympic Games in London.
