Jaime Munguia produces adverse VADA result

FORMER world champion Jaime Munguia has returned an adverse VADA test result following his victory over Bruno Surace, according to Ring Magazine journalist Mike Coppinger.

The 28-year-old exacted his revenge over Surace, 26-1-2 (5 KOs), earlier this month, securing a comprehensive unanimous decision win against the previously little-known Frenchman.

Before that, a stunning sixth-round stoppage defeat in their first encounter saw Munguia, 45-2 (35 KOs), find himself on the receiving end of last year’s most widely-discussed upset.

But now, it is possible that a performance-enhancing substance, detected by a Voluntary Anti-Doping Agency (VADA) test, may have assisted him in avenging that loss.

Coppinger wrote on a social media post earlier today: “VADA informed all relevant parties [on] Wednesday that Jaime Munguia’s A-sample returned an adverse analytical finding for exogenous origin of testosterone metabolites following a urine sample on May 4 when he defeated Bruno Surace, sources told [Ring Magazine].

“Munguia has 10 days to request analysis of his B-sample for exogenous origin of testosterone metabolites.”

Munguia lost to Surace in only his second outing after getting comfortably outpointed by Canelo Alvarez, who is now his stablemate, earlier last year.

The sixth-round finish arrived soon after the Mexican had built a strong lead on the judges’ scorecards, seamlessly gliding through his homecoming spectacle in Tijuana prior to the stoppage.

But then, in a somewhat unexpected turn of events, Munguia joined forces with Eddy Reynoso, the head coach of Alvarez, in a bid to rejoin the world scene at super-middleweight.

From there, the pair forged a simple but effective game plan, with Munguia utilising his technical prowess to outpoint Surace in their immediate rematch.

Munguia’s rematch performance was impressive. Now, the high-volume puncher has produced an adverse result, until the B-sample is tested for further confirmation.
