Former world champion Jaime Munguia cleared of failed PED test
Jaime Munguia will face no punishment from UKAD or BBBofC
Former WBO super-welterweight world champion Jaime Munguia (45-2, 35 KOs) will receive no punishment from UKAD or BBBofC for his failed PED tests, after testing positive for exogenous testosterone.
The failed PED test was a false positive, "caused by accidental contamination with pregnenolone, a legal, non-banned substance."
As a result, Mexican Munguia will rightfully not face any sanctions, and his win over Bruno Surace will remain unchanged.
Munguia was initially flagged for a banned substance by the Voluntary Anti-Doping Agency a few weeks after outpointing Surace in a rematch after the Mexican was stopped in December.
The 28-year-old proclaimed his innocence on social media and vowed he would clear his name.
Shortly after the initial positive test, Munguia's team requested that the B-sample be tested. That test also came back positive. However, after further review of the samples, Munguia's name was cleared, and he said he hopes to return to the ring before the end of the year.
"I want to thank the WBC for reviewing the complete scientific evidence and confirming there will be no investigation, charge, or sanction," Munguia said in a statement Tuesday. "We've been notified by the British Boxing Board of Control (BBBofC) that they appointed UK Anti-Doping (UKAD) as the body responsible for anti-doping regulation, testing, investigation and results management, and after their review of the full record, they reached the same conclusion.
"I did not cheat - the science proves it - and I am grateful to the WBC, BBBofC, and UKAD for acknowledging this truth. .I am ready to put it behind me and move forward with my career. I look forward to returning to the ring soon, and I deeply appreciate everyone - especially my family, team, fans and sponsors - who stood by me through this ordeal."
Munguia made his pro debut in 2013, fighting 25 times in Mexico until his American debut took place in 2017. He soon won his first title in February 2017 - the WBC Latino super-welterweight belt.
Just 15 months later, he was crowned WBO world super-welterweight champion in New York with a fourth-round KO of Sadam Ali. He made five successful defences of the strap, within just 16 months time, without ever losing it in the ring, choosing to vacate the belt to move up in weight.
He won a WBO Inter-Continental title up at middleweight; then challenged Canelo Alvarez for the undisputed super-middleweight championship in May 2024, after stopping Briton John Ryder in a defence of his WBC Silver crown three months prior.
The Mexican suffered a shock defeat to unheralded Frenchman, Bruno Surace, in December 2014 after being caught cold in the sixth round, but he came straight back with a revenge win in May 2025.
