LOS ANGELES >> Canelo Alvarez has withdrawn from next month’s middleweight title fight with Gennady Golovkin, two months after Alvarez twice tested for a banned substance.

The May 5 fight in Las Vegas was to have been a rematch of the draw they fought last September. But on March 5, Alvarez’s promoters, Golden Boy Promotions, announced he twice tested positive for the steroid clenbuterol in February. They blamed contaminated meat, and Alvarez agreed to random drug testing.

It was unlikely the Nevada State Athletic Commission would approve the fight after it temporarily suspended Alvarez, who could face a longer suspension.

Alvarez is to appear before the commission April 18 concerning the positive tests. Golden Boy President Eric Gomez said today the promoters were advised Alvarez likely would not be cleared to fight May 5.

“I have always been a clean fighter and I always will be a clean fighter,” Alvarez said today during a conference call. “I want to prove without a doubt that I have never intentionally ingested clenbuterol. I have nothing to hide and I want to be open and transparent through this process. . I have never taken illegal substances and this is no different.”

Golovkin is hoping to fight a different opponent at T-Mobile Arena on May 5, but it won’t approach the huge event that the rematch with Alvarez would have been. It’s possible the two could meet later this year, depending on any sanctions placed on the Mexican fighter.

Golovkin, of Kazakhstan, publicly doubted that tainted meat caused Alvarez’s positive test.

“Again with Mexican meat? Come on,” Golovkin said in March. I told you, it’s not Mexican meat. This is Canelo. This is his team. This is his promotion. … Canelo is cheating. They’re using these drugs, and everybody is just trying to pretend it’s not happening.”
