Canelo Alvarez has been banned for professional boxing for six months for failing two drugs tests earlier this year.
The Mexican middleweight tested positive for fat-burning substance clenbuterol in February and has now been handed a backdated suspension.
Alvarez denied the doping charges, claiming that the positive tests were a result of consuming contaminated meat, but cooperated with the investigation.
A hearing panel voted to hand the fighter a six-month ban rather than a year-long one because of his cooperation, reports BBC Sport.
Alvarez will be eligible to return to the ring on August 17.
