Frank Warren and Anthony Joshua are ‘in talks’ about a massive fight.

Anthony Joshua is ‘in talks’ for a mega-fight at Wembley Stadium, according to promoter Frank Warren.

Joshua sat ringside for last weekend’s 5 vs. 5 card in Riyadh, Saudi Arabia, where Warren’s Queensberry Promotions defeated Eddie Hearn’s Matchroom Boxing by a stunning 10-0 margin.

Willy Hutchinson defeated Craig Richards, Nick Ball dethroned Ray Ford for the WBA featherweight world title, and captain Hamzah Sheeraz stopped Ammo Williams, resulting in double points.

Daniel Dubois startled Filip Hrgovic, handing the Croatian his first professional defeat, and Zhilei Zhang knocked out Deontay Wilder in horrific fashion.

Joshua, who hasn’t fought since his destruction of Francis Ngannou last March, was on a scouting mission as he’s in the running to face one of the four heavyweights who were in action.

And according to Warren, his team are in talks with Joshua to face Dubois, who won the interim IBF world heavyweight title.

A version of the world heavyweight title was on the line for Dubois vs. Hrgovic, which was captured by the Brit.

Joshua appears set to meet Dubois for the interim IBF title at Wembley Stadium on September 21.

On talkSPORT, Warren revealed: “Daniel Dubois proved all his doubters wrong and won the IBF interim belt.

“He hopefully will be fighting AJ in the autumn, we’re working on that. He did well…

“We would love it to be in the UK, they’re two Brits, it would be a great fight to put on at Wembley.”

Daniel Dubois celebrates winning the interim IBF title after beating Filip Hrgovic.

The 72-year-old added: “We do have a press conference later on this month, hopefully then we can make some announcements.

“AJ was ringside and I was sitting next to him in fact. I said to him, ‘Right, come on, let’s get this on’.

“We’ve got discussions going on so hopefully we can get it over the line.”

Joshua is no stranger to fighting at Wembley Stadium, having fought Wladimir Klitschko and Alexander Povetkin at the home of English football.

Dubois, meanwhile, registered 15 wins in a row before succumbing to Joe Joyce. He then won four consecutive fights to earn a shot at Oleksandr Usyk.

The 26-year-old seemingly had Usyk hurt to the body before suffering a ninth-round stoppage.

But in his last two outings, Dubois has turned his fortunes around, pulling off the biggest wins of his budding career.

He stopped Jarrell Miller before scoring a huge win over Hrgovic.
