Jaime Munguía headlines May 2 card

Boxing cards usually sell you on titles, rivalries, and knockouts. This one also comes with a trust issue. Jaime Munguía fights Armando Reséndiz on Saturday, May 2, in Las Vegas, and the bout is suddenly carrying more scrutiny than a normal co-main because Reséndiz’s side keeps raising one point — they want drug testing. Add Canelo Álvarez showing up to support Munguía, and a strong undercard fight just got a lot louder. (boxing-social.com) ### What is this fight, exactly? This is the co-main event on the David Benavidez vs. Gilberto “Zurdo” Ramírez card at T-Mobile Arena. Reséndiz is defending the WBA super middleweight title against Munguía in an all-Mexican matchup, and the show is being carried on Prime Video pay-per-view, with DAZN also selling it. It’s part of a Cinco de Mayo weekend lineup that was already built around Mexico-vs.-Mexico fights. (boxing-social.com) ### Why did Munguía end up in this spot? Because this was not the original plan. Jermall Charlo had been lined up to challenge Reséndiz on May 2, but Charlo was pulled from the fight in March for undisclosed reasons. Munguía stepped in as the replacement, which changed the tone of the matchup right away — he’s the bigger name, the more proven 12-round fighter, and a much more commercially visible opponent. (espn.com) ### Why is drug testing suddenly part of the story? Because Munguía’s last win came with baggage. After beating Bruno Surace by unanimous decision in May 2025, he had a positive test that was later cleared as accidental contamination tied to pregnenolone, which is legal and not banned. That explanation closed the case on paper, but not in everyone’s min(espn.com)ust to remove doubt. (ringmagazine.com) ### What is Manny Robles actually saying? Basically — he is trying to frame this as fairness, not theater. In interviews this week, Robles said he is “all for testing” and wants an even playing field. He has also made clear that Reséndiz’s camp still has unanswered questions about how Munguía’s prior positive was resolve(ringmagazine.com)tra safeguards. (boxing-social.com) ### Where does Canelo fit into this? Canelo fits in through Eddy Reynoso. Munguía now trains with Reynoso, and Reynoso told TV Azteca that Canelo will be in attendance to support Munguía on fight night. That does not change the punches thrown in the ring, but it absolutely changes the spotlight. A co-main that already had title stakes and testing chatter now has one of boxing’s biggest stars attached to it at ringside. (tvazteca.com) ### Why does this matter for Munguía? Because this feels like a hinge fight. Munguía is 29, coming off a weird stretch — knocked out by Surace in 2024, then avenging that loss in 2025, then spending months clearing his name after the positive test. He has said everything is on the line here, not just a world title but his career direction. A win gives him a belt and a reset. A loss leaves the doubts hanging around even longer. (boxingscene.com) ### Why is Reséndiz dangerous? Because Reséndiz is not just a placeholder champion. He broke through by upsetting Caleb Plant in May 2025, and that win pushed him from spoiler territory into titleholder status. Robles thinks the Munguía fight could turn into an all-out war, which makes sense — Munguía likes pressure, Reséndiz has momentum, and neither side is talking like they came to survive. (ringmagazine.com) ### So what’s the real angle? The real angle is that this is no longer just a comeback-style title shot for Munguía. It’s a public credibility test. If he wins cleanly, with Reynoso in his corner and Canelo in the building, he gets a huge piece of his standing back. But until the bell rings — and maybe until the post-fight paperwork is done — the testing question is part of the event now. (ringmagazine.com)
