Amir Khan is willing to face Lamont Peterson again if the American passes a drugs test.
Khan lost his WBA and IBF light-welterweight titles to Peterson last December in a controversial points defeat and a rematch was axed when the new champion tested positive for synthetic testosterone.
The Bolton fighter will instead battle WBC champion Danny Garcia on July 14, but he has not ruled out another meeting with Peterson in the future.
"I would love to because at the end of the day it was a great fight, a great fight for the fans," Khan told eastsideboxing.com.
"I would love to fight Lamont Peterson again if he is off steroids, but if he is still on them he is a threat to my career and my life.
"Other than that if it's going to be fair and he's not going to take anything, it will be an easy win for us.
"I think that's what kept him in the fight so long, because if he was not on anything I think I would of stopped him in a couple of rounds.
"It shows that it helps an opponent when you take banned substances."
