Promoter Ben Shalom has made it clear that Amir Khan must first "prove he's not finished" before considering a rematch against Kell Brook.

Last month, Brook and Khan finally met in the ring after a decade long rivalry.

Brook rocked and stopped Khan in the sixth round of a pretty much one-sided fight.

There is an immediate rematch clause, but Khan has yet to officially exercise that option.

Khan is apparently eager to get a rematch with Brook.

However, Shalom would like to see Khan have an interim-fight to prove his worth for such a fight.

"Amir I think will fight," said Shalom to Sky Sports. "He will fight again, he wants to fight again. I think he has understood why it might be a tough sell to go straight back into a Kell Brook fight.

"I believe him that he was injured [against Brook]. I do believe that there were some issues with the camp and he only had 10 weeks. It's for him to prove he's not finished, it's for him to prove it's not just about the money, and therefore I think another fight to show that might be more appropriate before he takes on someone like Kell Brook."

Brook would like to return to the ring on a date in June or July.

The one fight Shalom would like to get for him is a catch-weight showdown with Chris Eubank Jr. The fight with Eubank actually coming off will depend on the weight more than money. Brook would like the fight to take place at a weight of 155-pounds, while Eubank, who competes at the middleweight limit, wants the fight to take place at something closer to 160-pounds and ruled out any possibility of getting down to 155.
