(March 18th) A major change has reshaped the undercard of the May 2 Cinco de Mayo weekend event at T-Mobile Arena, as Jaime Munguia will now challenge Armando Resendiz for the WBA super middleweight title after Jermall Charlo withdrew from the bout for undisclosed reasons.

The fight will serve as the co-main event to the cruiserweight championship clash between Gilberto 'Zurdo' Ramírez and David Benavidez during a PBC Pay-Per-View broadcast on Prime Video.

Charlo had been expected to challenge Resendiz, but his withdrawal—announced shortly after the matchup was initially reported—forced promoters to find a replacement. Munguia, a former junior middleweight world champion, quickly emerged as the new opponent.

The substitution alters the tone of the bout while keeping the event intact. While Charlo’s name carried championship pedigree, Munguia brings a reputation for activity and offensive pressure that could produce a more action-driven fight.

Resendiz will enter the bout making the first defense of the WBA super middleweight championship he earned following a breakthrough run in 2025.

His rise was highlighted by a major upset victory over former champion Caleb Plant in May 2025, a result widely considered one of the year’s biggest surprises. Resendiz was later elevated to full WBA champion when the title became vacant following a championship restructuring within the division.

Resendiz now 16-2 (11 KOs), the aggressive Mexican pressure fighter faces his most high-profile defense yet.

Munguia (45-2, 35 KOs) is seeking a world title in a second weight class after previously holding a belt at 154 pounds.

The 28-year-old has not fought since May 2025, when he defeated Bruno Surace by unanimous decision in a rematch that avenged a shocking knockout loss earlier in their rivalry.

That victory briefly came under scrutiny after a post-fight drug test produced an adverse finding, but the result was later ruled a false positive linked to a contaminated supplement, allowing the win to stand.

The change from Charlo to Munguia also transforms the likely style of the contest.

Resendiz is a relentless pressure fighter who attacks the body and thrives in close quarters. Munguia, known for high punch volume and durability, tends to engage rather than box cautiously.

The matchup therefore projects as a high-intensity battle of attrition rather than the more tactical contest that might have unfolded against Charlo.

Additional bouts are still being finalized for the undercard as promoters aim to build a Cinco de Mayo weekend lineup centered on prominent Mexican fighters.

For Resendiz, the bout represents a chance to validate his championship run against a proven former titlist.

For Munguia, it is an immediate opportunity to re-enter the championship picture and capture a world title in a second division.

Meanwhile, Charlo’s withdrawal adds further uncertainty to the career of the once-dominant middleweight champion, whose ring appearances have been sporadic in recent years.
