Daniel Dubois, the British professional boxer, has defeated Anthony Joshua, the two-time world champion, with a fifth-round knockout to retain his IBF world heavyweight boxing title.

The 27-year-old demolished his fellow Briton at a packed Wembley Stadium in the United Kingdom on Saturday night.

It was a nightmare outing for Joshua, 34, as Dubois floored the former heavyweight champion thrice in the first three rounds before eventually finishing him off after 59 seconds in the fifth round.

Dubois inflicted a fourth professional defeat on Joshua in front of 96,000 fans — the biggest crowd ever for a boxing event at the Wembley Stadium.

“I’ve only got a few words to say: Are you not entertained?” Dubois asked the crowd after earning the biggest win of his career.

“I’m a gladiator, I’m a warrior to the bitter end. I want to get to the top level of this game and reach my full potential.

“I’ve been on a rollercoaster ride. This is my time, this is my redemption story, and I’m not going to stop until I reach my full potential.”

When asked what went wrong, Joshua said: “Credit to him and his team. We rolled the dice at success and we came up short”.

“You know I’m pissed. You know I’m ready to kick up in the ring, but I’m going to keep my cool and keep very professional and give the respect to my opponent.”

Joshua was in a position to secure a possible fight against the winner of the December 21 fight between Oleksandr Usyk and Tyson Fury.

Dubois, 27, will now get that shot after improving to 21-3
