Earlier this month, middleweight contender Saul "Canelo" Alvarez was pulled from the WBC's rankings - because of his refusal to enter their Clean Boxing Program - which is run by drug testing agency VADA [Voluntary Anti-Doping Agency].

WBC President Mauricio Sulaiman has revealed that Canelo will return to his organization's rankings in the month of June - after Canelo recently signed up with VADA for a year-round drug testing protocol.

Canelo has been under fire since the month of March, after it was revealed that he tested positive for the banned substance clenbuterol in a pair of tests taken in February.

The Mexican superstar was going to fight WBC, IBF, WBA, IBO middleweight champion Gennady Golovkin on May 5 - but the contest fell out after Canelo was hit with a six month suspension by the Nevada State Athletic Commission.

"Already (Canelo) will return to the rankings in June. That's the regulation, if you're a part of VADA for the out-of-competition tests, you can be ranked. If you're not (in VADA), you can not be ranked, it's simple consistency," said Sulaiman to ESPN Deportes.

"Being enrolled in this program a positive step of clarity. It is clear and conclusive that he is intending to be a clean boxer, to be available 365 days a year, 24 hours a day, seven days a week - because you can get tested at any time."

Canelo will be capable of fighting by mid-August. He hopes to face Golovkin in a rematch on September 15th, as part of Mexican Independence Day weekend.

They fought last September to a controversial twelve round draw at the T-Mobile Arena in Las Vegas.

Golovkin returned to the ring on May 5 as planned, at the StubHub Center in Carson, California. In an HBO televised main event, he scored an easy two round knockout of junior middleweight contender Vanes Martirosyan.
