Eddie Hearn has put a price tag on how much Anthony Joshua would want for him to step aside from his heavyweight rematch for Oleksandr Usyk.
The promoter had previously revealed the pair were expected to collide once again in March time with the UK remaining the firm favourite for the location despite whispers of it being in Saudi Arabia.
Joshua surrendered the WBA, IBF, WBO and IBO titles to Usyk at the Tottenham Hotspur Stadium in September via unanimous decision.
While Joshua has activated his rematch clause, Hearn has said £40m would be the number to allow Usyk to fight Fury next.
"Seven figures? A million? If you want to get him not to fight Oleksandr Usyk you have to times that by 40... 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 said.
"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."
Fury is currently embarking on a UK Tour to celebrate his most recent victory over American rival Deontay Wilder.
The WBC titlist - who knocked Wilder out in round 11 of their trilogy bout in October - branded Joshua 'a p****' for not allowing him to take on Usyk next.
As it stands, Fury will be forced to take on his mandatory challenger next although it is unknown as to whether it will be Dillian Whyte - the current interim champion - after taking the WBC to an arbitration court.
Other contenders ready to step in for Whyte include fellow British contender Joe Joyce who is undefeated from 13 fights.
