EDDIE HEARN has flown into Saudi Arabia to hold advanced talks over a super-fight in December for Anthony Joshua.
Hosts in the Middle East are hoping to pit the heavyweight elite against each other in a tournament-style format.
It would see the prospect of Tyson Fury, 34, unifying the titles against Oleksandr Usyk, 36, after their failed talks to do so in April.
And Joshua, 33, would meet Wilder, 37, in an anticipated blockbuster years in the making.
The stunning and lucrative plan has now moved a step closer after Hearn landed in Riyadh for talks.
Joshua twice boxed in Saudi before, beating Andy Ruiz Jr, 33, in Diriyah in 2019 but losing to Usyk last August in Jeddah.
Both AJ, Wilder and their respected camps have given the mega-fight the green light.
And Usyk’s side are also on board with fighting Fury in the desert despite their collapse of talks earlier in the year.
A deal for the first ever four-belt undisputed decider broke down amid a row over the financials for a potential rematch.
Usyk is now set to face WBA mandatory challenger Daniel Dubois, 25, with Andy Ruiz Jr, 33, in talks to fight Fury in London.
But the Ukrainian’s promoter Alex Krassyuk has kept the door open to a future unification bout and passed the buck on their opposition.
Krassyuk told BT Sport Boxing: “Oleksandr Usyk and his team are known to be the easiest people to deal with in the world of boxing.
“So there’s only one thing still pending and it’s a complex personality who goes back and forth, playing his games to try and squeeze as much money as possible. That was the reason why Usyk called him greedy belly!”
