Anthony Joshua is set to sign a two-fight deal that would secure a blockbuster match with Tyson Fury in 2021, according to promoter Eddie Hearn.
Both British fighters hold major the belts in the heavyweight division and the pair are set to unify the division when they clash.
"It would probably be a two-fight deal," Hearn told Sky Sports. "Any deal between Fury and AJ, you run it twice.
"It is not a condition of the deal but it was in their deal with Deontay Wilder, and it is the biggest fight in boxing, so it is likely you will see that twice."
But AJ would defend his titles against Kubrat Pulev while Fury will complete his trilogy with Wilder.
"Wilder is not going to be stepping aside so [Pulev] is the fight for us," Hearn said.
"I had a conversation [on Thursday] saying: 'Wilder is not stepping aside, we will take care of that fight, you take care of the Pulev fight, but let's get a deal done for 2021'.
"We have no problem signing now to fight Fury in 2021."
The postponed Johsua and Pulev fight will not take place behind-closed-doors despite the global pandemic
According to Pulev's manager Ivaylo Gotsev, a new location and date will be announced in the next three weeks.
