Anthony Joshua showed guts and determination to make it to the fifth round against Daniel Dubois, and his belief that he could come back and win the fight was evident right up until he was sent to the canvas for the final time.

Joshua's plan went out of the window when he was floored by a powerful Dubois right-hand in the opening round. As per his promoter, Eddie Hearn, he was fighting on 'heart' from then on and demonstrated plenty of it.

Further knockdowns came in the third and the fourth, with Dubois taking an age to finish the job against a resilient AJ.

The knockout punch finally landed in the fifth, with boxing fans around the world and the 96,000 crammed into Wembley stunned by a blow which sent Joshua down harder than he has ever been down before.

Crowd footage circulating on social media shows the moments leading up to Dubois' devastating right-hand from a new angle. And 16 seconds before it landed, while backed into a corner, Joshua was seen showboating as he looked over and stuck his tongue out to a member of the audience.

The 34-year-old initially backed up his confidence by stinging Dubois with a precise right. But it was when he went in for the kill that the fight was ended for good.

Sensing an opportunity and moving forward, AJ wound up for a haymaker, but before it could land, Dubois' short, sharp shot landed flush on the chin. The 27-year-old retained his IBF world heavyweight title in the process, though he may have to fight Joshua again to keep hold of it.

"I think he will exercise that rematch clause, I think that's a given," said Matchroom's Hearn in the immediate aftermath. "He'll need a rest and it's a dangerous fight, this guy is growing in confidence all the time.

"He'll believe he can hurt Dubois, he'll believe he can beat him. But full credit to Daniel Dubois, he deserves all the credit, it was a great performance."

Hearn continued in the post-fight press conference: "I think that 2025 is going to be an interesting year for Anthony Joshua, one way or another, but he will definitely be back and whether it's against Daniel Dubois, Tyson Fury, whoever, you're going to be entertained."
