Munguia Denies Doping Despite Adverse Test Result
- Jaime Munguia's urine sample, collected after his unanimous decision victory over Bruno Surace on May 4 in Riyadh, revealed the presence of a prohibited substance.
- The positive test detected exogenous testosterone metabolites, leading Munguia’s team to request the opening of his B-sample within 10 days to confirm the result.
- Munguia, a 28-year-old former junior middleweight champion with a 45-2 record and 35 knockouts, won the rematch on the Riyadh Season card, which was under the Canelo Alvarez vs. William Scull main event.
- VADA informed all parties that Munguia’s A-sample showed an adverse finding for “exogenous origin of testosterone metabolites,” while Munguia insisted on Instagram he has never tested positive before and is willing to undergo further testing.
- If Munguia’s B-sample confirms the positive test, he faces possible suspension and the risk of his victory being overturned to a no contest, while his team’s official response is pending.
