Amir Khan is entitled to a rematch with Kell Brook, but Boxxer promoter Ben Shalom advised against it.
The two 35-year-old British former world champions fought last weekend after years of bad blood between them.
Brook emerged as the comfortable winner, stopping Khan in the sixth round after being in control for almost all of the match-up.
Both Khan and Brook could retire after the fight, it had been suggested, and Shalom hinted that Khan should now step away from the sport and certainly another chance.
“The problem we’ve got, and no one has mentioned it so far, is that Amir Khan has a rematch clause in his contract,” Shalom said to talkSPORT.
“It’s not something we would advise and it’s something we don’t think Amir should do, but he does have that option.
“We have heard murmurs from his camp that he was jet lagged and didn’t take Kell too seriously.
“I don’t think it will happen, but it’s not something in our control.
“It is something we agreed to before the fight, something Kell agreed to before the fight and he has three weeks to decide if he wants to fight him again.
“Amir got demolished in that fight and I would expect that to happen again.
“Technically he would be entitled to that rematch.”
However, Shalom said that Khan had yet to make it clear what his plans were.
“I think the only person who can sell that is Amir. I don’t know what’s in his head or what happened,” he said.
“What I saw was a one-way street and I felt Amir was finished.”
