Exclusive – Billy Joe Saunders ‘knows’ he boxed an opponent who cheated using drugs

WBO middleweight world champion Billy Joe Saunders claims he “knows” that one of his past opponents was cheating by using performance-enhancing drugs against him.

The unbeaten 160lbs title-holder made the bold accusations ahead of his fight with Martin Murray on June 23.

“I know I have boxed an opponent on some sort of drug. I know I have,” Saunders told Jim White on talkSPORT.

“I would put my house down that he was on something when I boxed him.

“I’m not stupid, I’ve been in this sport a long time. I can look at somebody and know what’s going on.

“I’m not saying recently, but I know in my career I’ve boxed someone who took a shortcut... I just 100% know.”

Recently in the middleweight division, Mexican superstar Canelo Alvarez was suspended for six months after testing positive for Clenbuterol.

As a result, his scheduled May 5 rematch with Gennady Golovkin was cancelled, although it now looks likely to take place in September instead.

“I think they should’ve taken more action against him because a six-month ban was just cancelling a date for him he’s then free to fight six months after,” declared Saunders.

“It’s just unacceptable and not a good example to set to young fighters in the game.

“Even on his ban, he will still announce a fight. Is it a ban really?”
