LOS ANGELES — Middleweight boxer Canelo Alvarez has tested positive for a banned drug, and his promoters blame contaminated meat.
A voluntary test showed Alvarez had traces of clenbuterol. A statement from Golden Boy Promotions said the amount was consistent with meat contamination that has impacted athletes in Mexico and China.
Daniel Eichner, director of the World Anti-Doping Agency-accredited laboratory that conducted the test, wrote Monday: "These values are all within the range of what is expected from meat contamination."
Alvarez is scheduled for a rematch with middleweight champion Gennady Golovkin on May 5 in Las Vegas, a highly anticipated fight after their draw last year.
Alvarez will move his training camp from Mexico to the United States and submit to additional tests, Golden Boy said.
