AMIR KHAN is calling for more random drug testing in boxing to KO drug cheats.

The sport is reeling from a series of high-profile boxers busted for using banned substances.

Khan was left without a fight at short notice in May when American Lamont Peterson tested positive for synthetic testosterone.

Peterson has now been stripped of the WBA light-welterweight title he won off Khan with a disputed points decision in December.

Khan, 25, has been twice randomly tested ahead of Saturday’s WBA-WBC light-welterweight title clash with American Danny Garcia in Las Vegas.

And the Bolton star wishes boxing officials worldwide would increase tests to crack down on cheats.

He said: “I’ve had two random drug tests in camp and expect I will have one just before thefight. I don’t mind doing them and think it should happen for all fights.

“There’s a lot of drug cheats in boxing right now.

“People pointed the finger at me because I was in Manny Pacquiao’s camp and did so well so quickly after the Breidis Prescott defeat. People started saying I was on something but I have proved I’m a clean fighter.”

Khan is confident of winning back his old WBA belt he lost to Peterson and the WBC belt from Garcia, and he added: “We don’t usually see two young guys facing each other at this stage of their careers – but this is exactly the sort of fight boxing needs.”
