American boxer Deontay Wilder secured a split decision victory over British fighter Derek Chisora in a heavyweight bout at London's O2 Arena on April 4, 2026. The contest, attended by approximately 20,000 spectators, featured two veteran fighters past their prime, with Wilder demonstrating greater composure despite Chisora's persistent forward pressure. Wilder, age 40, landed significant punches that opened a cut above Chisora's left eye and scored a knockdown in the eighth round. Chisora, age 42 and weighing a career-high 19 stone, showed remarkable resilience but struggled with Wilder's counterattacks. Judges scored the fight 115-111 and 115-113 for Wilder, with one judge favoring Chisora 115-112. The event drew notable attendees including former heavyweight champion Anthony Joshua, musician Noel Gallagher, and actor Matt Smith. Chisora indicated this might be his final professional match, a claim he has made previously, while Wilder expressed respect for his opponent and suggested inviting him to Alabama. The undercard included victories for Viddal Riley, Denzel Bentley, Matty Harris, and Ashton Sylve.
