Jaime Munguia tested positive for banned substances after his win over Bruno Surace on May 4. The World Anti-Doping Agency (WADA) found external testosterone metabolites in Munguia's system.

WADA told Munguia's team about the failed test on Wednesday night. The Mexican boxer now has 10 days to ask for a second test of his B sample. If the B sample also comes back positive, Munguia could lose his victory and face a suspension of six months to a year.

Munguia took to Instagram to defend himself. He said:

"I am surprised like everyone else. I am a clean athlete. I am willing to take all the necessary tests."

His team is working on a formal response and plans to request analysis of the B sample.

Bruno Surace, Munguia's opponent in the May 4 fight, isn't buying it. He told The Ring:

"There is no place for cheating in boxing. The sport is dangerous enough. I knew he couldn't beat me on a level playing field. I am confident that the result of the fight will be reversed immediately."

This isn't the first time a boxer has faced this kind of problem. Ryan Garcia dealt with a similar situation last year.

The news has sparked criticism on social media, with many pointing fingers at Canelo Alvarez's team, especially Eddy Reynoso. Some fans think it's more than just a coincidence that another fighter associated with Reynoso has failed a drug test.

Golden Boy Promotions, Munguia's promoter, hasn't made any official statement about the situation yet.

As the story unfolds, boxing fans will keep a close eye on the results of the B sample test and any decisions made by boxing authorities.
