Eddie Hearn, promoter for welterweight Conor Benn, is hoping everything comes together to finalize a fight with Chris Eubank Jr. for a date in December.
They were scheduled to fight last October, at a catchweight of 157-pounds, but the event was called off only days before their fight date - after news broke that Benn had tested positive for a banned substance.
Their famous fathers, Nigel Benn and Chris Eubank Sr, fought 30 years ago in historic fights on British soil.
"Eubank Jr v Benn is not as big as Tyson Fury v Anthony Joshua but it's not a million miles away," Hearn told 5 Live Boxing.
"It's an all-time British classic [the fight between their fathers], it's the biggest fight for Eubank Jr and it's the biggest fight for Benn. Hopefully we can get that done for December. We're in talks with [Eubank's promoter] Kalle Sauerland."
Earlier this year, the 26-year-old Benn was cleared to return to the ring by the National Anti-Doping Panel.
However, that decision has been appealed by UK Anti-Doping and the British Boxing Board of Control.
"He's cleared to fight everywhere at the moment, he's not suspended, he's had that suspension lifted, he won his case," Hearn said.
"The British Boxing Board of Control are appealing and that's expected to be later this year but as of now, he's free to fight in the UK, he's free to fight in America, he's licensed in America as well, there are discussions about him jumping on the September 30th card in London, but there's also discussions about him fighting in Orlando on September 23rd."
Hearn believes the Benn vs. Eubank fight is much bigger now than it was last year.
"Eubank Jr vs. Benn is an absolute monster and that's why we're looking at Wembley Stadium," Hearn said.
