Overview

• The Voluntary Anti-Doping Association confirmed Munguia’s May 4 urine sample contained exogenous testosterone metabolites following his rematch win over Bruno Surace.
• Munguia has maintained his innocence, suggesting the result stems from contamination and pledging to undergo any further testing to clear his name.
• Bruno Surace has publicly demanded that Munguia’s unanimous decision victory be overturned to a no-contest if the B-sample also returns an adverse finding.
• Former boxing champions Jermell Charlo and Jeff Mayweather have criticized trainer Eddy Reynoso’s camp and called for year-round testing and tougher sanctions in the sport.
• If Munguia’s B-sample confirms the initial result within the ten-day window, he could face suspension and see his win nullified.
