Promoter Eddie Hearn is still trying hard to get Amir Khan in the ring with his domestic rival, Kell Brook.
Brook returns on Saturday night in Sheffield, against top rated contender Michael Zerafa.
It was believed that Khan and Brook would collide in the first quarter of 2019, but now that plan is in jeopardy after Khan was offered a $5 million guarantee to face Terence Crawford for the WBO welterweight title on March 23 at Madison Square Garden in New York City.
Hearn is not very involved in the Khan-Crawford negotiations.
But the British promoter makes it clear - that Khan would make a lot more money for a fight with Brook.
Despite what Khan believes, Hearn warns that it's now or never to do the fight with Brook.
"There's talks for the Crawford fight. I've spoken to Bob Arum, I've spoken to Amir," Hearn told Sky Sports News.
"I'm not having too much to do with that side, because I don't want that fight. I want the fight that's going to create the legacy in this country, and that's Brook against Khan. It's a massive fight where Amir can make twice as much money as the Crawford fight.
"But Amir seems to think the Brook fight is always there. It's not. This is now or never, this is the last chance. Let's give the British public what they want. If Amir can beat Kell Brook, he could fight Crawford after for more money than he's going to get now. I don't see any excuses and Kell's right. I've been with him a long time and I signed Amir Khan with a view to make this fight with Kell Brook. I believe the British public deserve this fight.
"Amir's got options, Kell's got options and they are going to make their decisions. Right now I think it's probably 50-50 whether he fights Crawford or Brook. But like I said, as far as I'm concerned this is the fight, Kell Brook."
