Carl Froch and George Groves are in talks over a world title fight later this year.
Groves is the mandatory challenger for Froch's IBF super-middleweight belt, and the champion has been given a July 12 deadline to agree a meeting or risk losing his title.
Froch, who is also the WBA's Super champion, previously said he would not give Groves a 'free shot' and hinted he would prioritise rematches with Andre Ward and Mikkel Kessler above a date with his unbeaten domestic rival.
But that stance has softened given Groves' mandatory status and Eddie Hearn, who promotes both fighters, has revealed discussions are already under way.
He said: "We are in talks regarding a potential blockbuster domestic fight later this year.
"Both fighters have plenty of options and, although it's a fight we originally envisaged for next summer, if it makes sense for both fighters neither has a problem with making it happen."
Groves was impressive in victory over Noe Gonzalez in May on the undercard of Froch's revenge mission against Kessler.
The 25-year-old is yet to fight for a world title having pulled out of a challenge for Robert Stieglitz's WBO belt last year.
