Former junior middleweight titleholder Jaime Munguia’s win over Bruno Surace on May 4 could be in jeopardy after he tested positive for a banned substance following a post-fight urinalysis.
A representative from Munguia’s team told ESPN KnockOut’s Salvador Rodriguez on Thursday that they received the VADA notification on Wednesday night regarding exogenous testosterone metabolites in Test A and that they will officially respond. The representative from Munguía’s team said they will soon request that Test B be opened.
Munguia (45-2, 35 KOs) officially has 10 days to request analysis of Test B for exogenous origin of testosterone metabolites. If his B-sample also returns an adverse finding for the banned substance, the former champion could see his victory by decision overturned to a no contest and face a suspension ranging from six months to one year.
Munguia’s promoter, Golden Boy Promotions, has not responded to ESPN’s request for comment.
Munguia avenged a stunning sixth-round knockout loss to Surace in December with a wide decision win in the rematch earlier this month on the Riyadh Season card that was headlined by Canelo Alvarez’s win over William Scull.
