Frank Warren insists "everyone wants" Anthony Joshua to step aside from his rematch with Oleskandr Usyk to set up an undisputed fight with Tyson Fury.
Joshua's second fight with Usyk seemed set in stone when the Brit triggered the rematch clause after losing his heavyweight titles to the Ukrainian in September.
But when Fury made the first defence of his WBC title by stopping Deontay Wilder in their trilogy, his promoters pushed for an undisputed fight clash with Usyk.
Hearn - who originally played down the fight - has now admitted talks are ongoing but it would take a massive £40million for it to happen.
And Warren thinks that Fury vs Usyk is the fight "everyone" wants to see next.
"There's been talks going on for a while now and it's all got to come to fruition, it's got to move on now," Warren told iFL TV.
"It seems to me there is a will to make this happen and hopefully if we can get everybody to sign an agreement, without announcing it, we can move forward.
"Until it's signed it don't mean nothing. There is a will and we all want it, everybody wants this fight between Tyson and Usyk. Everybody."
Fury is still expected to be ordered to face domestic rival Dillian Whyte next, despite the WBC delaying their decision to rule White as mandatory challenger.
Usyk - who is expected to be a favourite in a rematch with Joshua - would "be happy" to fight Fury if Joshua is to step aside, according to his promoter Alex Krassyuk.
Fury's co-promoter Bob Arum has revealed that Saudi Arabia wants to stage the potential fight between 'The Gypsy King' and Usyk in March of next year.
And Hearn said whilst talks are ongoing about a potential step aside deal, Joshua is yet to have his say on the matter.
"At the moment there is communication between the two teams to say is it something... and the answer is AJ has not been spoken to about this yet," Hearn told Boxing King Media.
"I'll deal with it and when I feel there's an opportunity for Anthony and 258 [Management] we'll sit down with them and present it to them but I won't do that until it's the right opportunity.
"If there's a route and an offer and it makes sense then we'll see but right now, it's just conversations between the camps.
"At the moment Anthony Joshua is fighting Oleksandr Usyk and that's the situation."
