The International Boxing Federation will speak to Lamont Peterson about his failed drug test before deciding whether to strip him of their light-welterweight title and potentially return it to Amir Khan. Khan today called for the return of his WBA and IBF titles after claiming Peterson's test proved he was "a cheat".
It emerged earlier this week that Peterson, who controversially beat Khan in December to capture the Bolton fighter's belts, had tested positive for synthetic testosterone, which is listed as a banned steroid.
Their rematch scheduled for May 19 has subsequently been cancelled, with Khan's American promoter Richard Schaefer, CEO of Golden Boy Promotions, is calling on the boxing authorities to "do the right thing" and rule the first fight a no-contest.
The WBA have yet to comment while a spokesperson for the IBF told Press Association Sport the body are reluctant to make a formal statement until hearing all of the evidence over the coming days.
"We are still waiting to receive all the information from the Nevada State Athletic Commission, as well as to speak with Lamont Peterson," they said.
Khan insisted: "The Nevada Commission have taken the license off Lamont Peterson and they don't want him to fight in the next fight. So I think whoever I fight next they'll put the titles on the line or we still go through the process and we might get the titles back and the fight that we had last time will be a no-contest."
Khan admitted the news of Peterson's positive test had come as a "big shock," but added: "The truth's come out now and it just proves that Lamont Peterson was a cheat really. It hurt me more than anything because I really did want to go in there and put on a performance and show the world how good Amir Khan is."
"I'm already at the right weight and it was a tough, tough training camp. I was so fit and looking forward to this fight. I wanted this fight even when I heard he failed his drugs test. I did everything to get the fight on, but my parents and my team said to me 'Look, at the end of the day Amir, it could be a risk to your life. It's not going to be fair to step into the ring with someone who is gonna be on drugs and gonna be cheating'.
"The next fight for me will be June, July. I've got a meeting with Golden Boy Promotions over the next few days and hopefully we'll set a date."
