Oleksandr Usyk successfully defended his undisputed heavyweight world titles by defeating Daniel Dubois via a fifth-round knockout at Wembley Stadium in London on July 19, 2025. The rematch, highly anticipated after Dubois's previous upset against Anthony Joshua, was broadcast live exclusively on DAZN. Usyk, who has won world championships at both cruiserweight and heavyweight, maintained his composure throughout the fight despite Dubois's aggressive tactics, including a moment where Dubois screamed in Usyk's face. The Ukrainian champion, who briefly served in his country's army during the Russian invasion, showcased his skill and resilience in front of a London crowd. Dubois entered the fight feeling "unstoppable" and aimed to claim the undisputed crown, but Usyk's performance reaffirmed his status as the reigning heavyweight champion.
