Promoter Eddie Hearn has confirmed negotiations for a fight between David Haye and Tyson Fury are close to completion.
Britain's two top heavyweights look set to go toe-to-toe in a bout this autumn and Haye's co-promoter Hearn revealed: "It's now a case of getting both fighters to cross the line."
He told the Daily Star: "It is a fight that will have enormous interest and it could generate one of the biggest pay-per-view figures of all time.
"I believe both fighters want the contest to take place because every fighter believes they can beat another fighter.
"We are now at a stage where this is close to happening. It's a brilliant fight between a former world champion and an up-and-coming prospect in Tyson Fury.
"If this fight is going to happen it will be sorted out by the end of this month, that's for sure."
Fury recently pulled out of a fight with the unbeaten Bulgarian Kubrat Pulev, which was set to earn the winner a shot at the IBF champion, Wladimir Klitschko.
Fury's uncle and trainer Peter admitted the fight would only not go ahead if there were problems on Haye's side.
He said: "We want Haye. If the fight does not happen, it won't be down to Tyson."
Haye has previously claimed he would only return to the ring to face one of the Klitschko brothers.
