Usyk knocks out Dubois to become undisputed heavyweight champion - ESPN

LONDON — Oleksandr Usyk ruthlessly knocked out Daniel Dubois in Round 5 to become undisputed world heavyweight champion once again on Saturday.

The Ukrainian became the first men's boxer to become an undisputed champion for a third time, following previous reigns at cruiserweight (2018) and heavyweight (2024), after he floored Dubois twice in Round 5 in front of approximately 90,000 at Wembley Stadium.

Usyk won Dubois' IBF title, to add to his WBC, WBA and WBO belts, in a fifth title defence.

Usyk first sent Dubois to the canvas with a right to the head for a count before flattening Dubois with a left hook.

It was proof (if proof were needed) that Usyk is the best heavyweight of his generation, having previously beaten former champions Anthony Joshua and Tyson Fury twice each.
