As previously reported, promoter Eddie Hearn of Matchroom is targeting a heavyweight showdown between former world champion Tony Bellew and Tyson Fury in 2018.
Hearn has spoken to both fighters about agreeing a deal and there is interest on both sides.
Bellew was scheduled to fight next month in a rematch with David Haye, who withdrew with a bicep injury. While a Haye rematch is being rescheduled for next March or May - there is guarantee the fight will actual happen.
Hearn is very interested in working with Fury, who the promoter claims is a free agent.
Fury (25-0, 18 KOs), a former WBO, WBA, IBF, IBO heavyweight champion, has been out of the ring since shocking Wladimir Klitschko for the belts in November 2015. Fury dropped the titles last year to focus on the state of his mental health.
He is currently training for a planned return in 2018 and aims to reclaim his license to box in the next few weeks. He has a hearing scheduled with UK-Anti Doping, who claim the boxer tested positive for a banned substance in early 2015.
While there is a serious difference is size, Bellew feels confident that he can beat Fury - and Hearn believes his boxer has chance of pulling it off as well.
"Tony believes he has the style to beat Fury. And Fury is not the puncher that Deontay Wilder or Anthony Joshua are. When you go up from light-heavyweight to cruiserweight to heavyweight, your big disadvantage is the punch power," Hearn told Sky Sports.
"Fury is extremely skilled but he is not a big puncher. I'm not saying he isn't a puncher. But he isn't a devastating one-punch knockout artist, like the others. So Tony believes he can beat him."
According to Hearn, Haye appears to be very eager to reschedule the rematch and get revenge on Bellew for the March TKO defeat.
"Haye is extremely driven to make the [Bellew rematch]," Hearn said. "He has a clear mind, he is an athlete, and he will do everything he can to be 100 percent ready for Bellew."
