The president of the World Boxing Council, Mauricio Sulaiman, is pleading with both Canelo Alvarez and Gennady Golovkin to turn away from the issue of clenbuterol and simply focus on what will happen in the ring on September 15 - when the two boxers are scheduled to collide in a rematch at the T-Mobile Arena in Las Vegas.

For several months, Golovkin has been slamming Canelo for a pair of drug tests which came up positive for clenbuterol back in February - and caused their initial May rematch date to fall apart.

Golovkin accused Canelo is being a longtime user of performance enhancing drugs.

Canelo has stood firm on his explanation of consuming contaminated meat.

To prevent any negative pre-fight publicity, Sulaiman wants the two boxers to focus on the fight - and forget the past.

"I feel that that (Canelo's drug testing issue) is already in the past. The tests did not show that he ingested (intentionally) a prohibited substance, everything indicates that it was contaminated by means of food, a number of subsequent tests have been done in which he was clean, and I think that chapter should now be turned over," Sulaiman said to ESPN Deportes.

"The attention must already be focused on what happens in the ring, and if Canelo wins, he should be recognized for his victory. Canelo has already signed up for the VADA anti-doping program (Voluntary Anti-Doping Agency). The fight will be inside the Clean Boxing Program and surprise tests will be made for both.

"He has to prove that he can beat Golovkin, Canelo is already a mature and experienced boxer, he is a boxer who has reached some very high places, but the champion is Golovkin and he has to show that he can deal with him and beat him."

Sulaiman confirmed that for this fight there will be a special belt adorned with Chiapas textile details.
