Positive Test for Jaime Munguia
In a significant turn of events, Jaime Munguia, the former champion of the WBO super welterweight division, has allegedly tested positive for a banned substance following his recent victory against Bruno Surace. The incident occurred after their rematch on May 4, 2025, at The Venue in Riyadh, Saudi Arabia.
Details of the Incident
According to information released by Ring Magazine, Munguia’s urine sample collected by the Voluntary Anti-Doping Association (VADA) revealed an adverse finding for testosterone metabolites of an exogenous origin.
Should Munguia’s B sample confirm the original findings, he faces potential repercussions from the British Boxing Board of Control, which regulates the bout. He has a window of 10 days to request the testing of his B sample. Furthermore, his unanimous decision win over Surace is now under scrutiny and could be ruled a no-contest as a result of this doping violation.
Background of the Fights
This development casts a shadow over a fight that was a significant comeback for Munguia. In their first encounter last December, Munguia was unexpectedly defeated by Surace, who delivered a stunning knockout in the sixth round despite Munguia being the overwhelming favorite. That bout had positioned Surace as a candidate for Upset of the Year.
In the rematch, Munguia had switched trainers, enlisting the help of famed boxing coach Eddy Reynoso, known for guiding Saul “Canelo” Alvarez. This strategic change appeared to pay off as Munguia employed a more disciplined approach, securing a clear unanimous decision victory.
He effectively utilized a heavy jab while carefully looking for openings, contrasting sharply with his more reckless style from the previous encounter. The fight was co-headlined alongside Alvarez’s title challenge against William Scull, marking a pivotal moment in Munguia’s career.
Implications for Munguia’s Future
As the boxing community watches closely, the implications of this positive test could have far-reaching effects on Munguia’s reputation and future in the sport.
