In the last few days, domestic rivals Amir Khan and Kell Brook have traded words over a potential showdown for 2019.
According to Khan, both sides have agreed to do the fight at the welterweight limit of 147-pounds - with a 10-pound rehydration clause on the morning of the fight.
Both boxers are promoted by Eddie Hearn, who wants to make the fight finally happen in the first quarter of next year.
Hearn has been trying to make the contest for the last five years.
Things became a step close when Khan signed with Hear earlier this year.
"We are (edging closer) actually," Hearn said to Sky Sports.
"It's the first time where we've probably actively negotiated and it has never happened before. Probably in five years trying to make this fight we've never been at a stage where we are actually going back and forth with information, planning dates, and things like that.
"There is a long way to go, but I do believe now that both guys have got it in their head that that fight will happen in February or March next year. Kell will probably box in Sheffield on December 8. He hasn't boxed since March, Amir obviously just boxed and I am hopeful and excited that this fight, that has eluded us for so long, could be close to happening."
Hearn indicates that Brook would like to make the fight for a catch-weight of 150-pounds.
But Khan is not going to budge on the welterweight limit of 147.
And as far as a rehydration clause, Hearn says there is nothing finalized as of yet for that clause.
"Kell would like to fight at 150lbs but Amir has got a point: 'I am a welterweight, if you want this fight, come to my weight' - and Kell can make 147," Hearn said.
"He's already in camp and has been for a long time because he knows he can't afford to make any mistakes if he's going to make 147. He can make it, there is talk of a rehydration clause but nothing is confirmed on that.
"It's not going to be easy, both guys are going to want their advantages going into this fight, but I just want to get it made. When those two come face to face and we announce that fight it's going to be a very special moment for British boxing, so fingers crossed we can get it over the line."
