In a developing doping controversy, it has emerged that Jaime Munguia failed drug test following his May 4 super middleweight victory over Bruno Surace, according to the Voluntary Anti-Doping Association (VADA). Munguia’s A-sample from the post-fight urine test showed evidence of a metabolite linked to exogenous testosterone indicating a synthetic form of the hormone was present in his system. This adverse finding has cast a shadow over the 26-year-old’s comeback win. That triumph came just months after Munguia suffered a stunning knockout loss to Surace in their first meeting last December.
Jaime Munguia Failed Drug Test Confirmed by VADA
VADA officials confirmed this week that Jaime Munguia’s initial sample returned an adverse analytical finding. Laboratory testing detected a testosterone metabolite of exogenous origin, meaning it was not produced naturally by the athlete’s body. Such a substance is banned in boxing due to its performance-enhancing properties. The sample was collected as part of standard post-fight anti-doping protocols on May 4, and the positive result now puts Munguia’s recent victory under scrutiny.
Rematch Victory After Upset Loss
Surace had stunned Munguia and the boxing world in their first bout last December, knocking out the former champion in a sixth-round upset. That outcome was later honoured as The Ring magazine’s 2024 Upset of the Year, given Surace’s underdog status. Munguia secured an immediate rematch, and on May 4 he avenged the loss by defeating Surace via unanimous decision in Riyadh, Saudi Arabia. The hard-fought victory was meant to restore Munguia’s momentum, but it now risks being tainted by the doping revelation.
Next Steps and Awaiting Response
Under anti-doping protocols, Munguia has 10 days from the notice of the adverse finding to request analysis of his B-sample. The B-sample a sealed second portion of the original urine sample would confirm the result if it also tests positive for the banned substance.
Should the B-sample uphold the positive test, Munguia could face disciplinary action and even have his win over Surace overturned by boxing authorities. For now, the fight’s result remains official and no sanctions have been announced pending further testing. No official comment yet from Munguia or his team on the situation.
