Eddie Hearn will meet with Anthony Joshua and his management team to discuss step aside talks for a potential undisputed fight between Tyson Fury and Oleksandr Usyk.
Joshua is close to agreeing a £15million step aside fee for his rematch with Usyk to allow the fight, according to The Telegraph.
The Brit lost his heavyweight titles for the second time in four fights when he was outpointed by Usyk last September.
He immediately triggered the rematch clause to face the Ukrainian with their second fight targeted for spring, but that could seemingly be off amid the step aside talks.
Fury has been ordered to defend his WBC title against mandatory challenger Dillian Whyte next, with the purse bids being delayed for a third time as they now take place on Wednesday.
And Hearn said they will discuss several proposals for Joshua's next fight on Tuesday.
"I'm meeting with AJ and 258 management [on Tuesday] to go through plans for his next fight. We have a number of proposals and options to discuss," he told Sky Sports.
"The goal remains the same of course - to re-capture the world heavyweight crown."
Usyk's manager Alex Krassyuk admitted little has changed since talks of an undisputed fight with Fury last year and the Ukrainian is still open to the change in opponent.
"We are in talks regarding Fury fight since November," he said.
"And though AJ gave his consent (according to Telegraph) we still have not reached the final point in negotiations and unless we get it - AJ rematch remains the basic option for us."
Whyte will also need to accept a step aside fee to allow the undisputed clash to happen, with the Daily Star reporting he wants £5million.

And Hearn thinks Whyte being called as the WBC mandatory challenger has caused problems for the undisputed fight.
"Talks were ongoing for Fury to fight Usyk and AJ to fight the winner but then Dillian Whyte got called as mandatory and had to come into the talks, which made it a lot harder and everyone gave up," he told Boxing Social.
“The plan now is AJ vs Usyk and Fury vs Whyte but those other talks do still rumble on, if I had to bet on the next fights that take place, it would be the two scheduled fights taking place.
“But there is a strong desire to find a way to have an undisputed fight with AJ fighting the winner - and without Dillian I think this would have happened.”
