Oleksandr Usyk secured a dominant victory over Daniel Dubois with a fifth-round knockout at Wembley Stadium on Saturday, becoming the undisputed heavyweight world champion.

The Ukrainian boxing star, now 38, maintained his unbeaten professional streak — extending it to 24 fights — by adding Dubois’ IBF title to his collection of WBA, WBC, and WBO belts.

Early in the fifth round, Usyk sent the younger Brit crashing to the canvas and sealed the win just 1 minute and 52 seconds in, delivering a signature left hook that Dubois couldn’t recover from.

Celebrating the triumph with his team, Usyk dropped to his knees in the ring, later joking: “38 is a young guy, remember!”
