Canelo Alvarez tests positive for Clenbuterol ahead of rematch with Gennady Golovkin
Canelo Alvarez has tested positive for trace levels of Clenbuterol ahead of his rematch with Gennady Golovkin in May, according to Golden Boy Promotions.
The Mexican took part in a voluntary testing programme which found evidence of the drug which was "consistent with meat contamination that has impacted dozens of athletes in Mexico over the last years".
Daniel Eichner, director of the World Anti-Doping Agency-accredited lab that conducted the tests, said "the values are all within the range of what is expected from meat contamination".
Golden Boy, Alvarez's promoters, have notified the Nevada State Athletic Commission and Golovkin's promoter and the 27-year-old will move his training camp from Mexico to the United States.
Alvarez said: "I am an athlete who respects the sport and this surprises me and bothers me because it had never happened to me.
"I will submit to all the tests that require me to clarify this embarrassing situation and I trust that at the end the truth will prevail."
