OLEKSANDR USYK vs UNDEFEATED BOXERS

I featured the Ukrainian boxer, former olympic gold medalist, undisputed world cruiserweight champion and now the current IBF, IBO, WBA and WBO world heavyweight champion Oleksandr Usyk. Before climbing up in heavyweight he first became the cruiserweight title by defeating undefeated boxers such as Krzysztof Glowacki, Michael Hunter, Mairis Briedis and Murat Gassiev.
