Cruiserweight Championship Main Event: Jai Opetaia vs Brandon Glanton

History will be made in the main event of Zuffa Boxing 04, as Ring Magazine cruiserweight champion Jai Opetaia takes on top 10-ranked contender Brandon Glanton for the inaugural Zuffa Boxing and Ring Magazine cruiserweight titles.

It’s a landmark moment for Opetaia (29-0, 23 KOs), who was the first world champion signed to Zuffa Boxing. Now the undefeated Aussie, who already holds the record as the longest-reigning Ring Magazine cruiserweight champion of all time, will look add a Zuffa Boxing championship belt to his collection.

Opetaia’s last outing saw him defeat Huseyin Cinkara via eighth-round knockout as he made the seventh defense of his Ring Magazine belt. He’ll look to take that tally to eight and collect a Zuffa Boxing championship in the process.

Standing in his way is hard-hitting Glanton (21-3, 18 KOs), who defeated Marcus Browne via TKO last October. The 34-year-old challenger has claimed each of his last seven victories inside the distance, and has 18 knockouts from his 21 career victories. He’s also never been dropped, and his iron-chinned resilience will receive a stern test against Opetaia, who has knocked out 23 of his 29 foes so far.

The pair will do battle in a historic title fight that is set to kick off a brand new era of champions, but only one can write their name in the history books as the first-ever Zuffa Boxing champion.

Co-Main Event: Ricardo Salas vs Jesus Saracho

Welterweights take center stage in the co-main event of the evening, as Mexican rivals Ricardo Salas and Jesus Saracho go head-to-head over 10 rounds at 147 pounds. 

Salas (23-2-2, 17 KOs) hasn’t tasted defeat in his last nine fights, notching seven wins and two draws in a run that stretches back to 2021. He’ll take on Saracho (16-2-2, 12 KOs), a southpaw with a 75 percent knockout rate who fought three times in 2025, drawing one and winning his last two. 

Now the two compatriots will face off as they look to make the first step up Zuffa Boxing’s welterweight ladder.

Main Card Bout: Adan Palma vs Pablo Rubio Jr

The three-fight main card will kick off with an eight-round featherweight matchup as undefeated 14-0 prospects Adan Palma and Pablo Rubio Jr do battle in their respective Zuffa Boxing debuts.

Palma had a busy 2025, kicking off with a split-decision victory over Sharone Carter before claiming successive knockouts of the previously undefeated Alfredo Castro Villafuerte, journeyman Daniel Olea, and Judy Flores.

Now he’s set to face Rubio, who returned from a two-year layoff with a sixth-round knockout of Alfredo Cruz in a fight he had dominated throughout. 

The California-based featherweights will clash as both men battle to hang on to their undefeated records. But, as the old adage goes, someone’s 0 has got to go…

Preliminary Card Bouts

Vlad Panin vs Shinard Bunch

Experienced welterweights top the preliminary card lineup as Vlad “Superbad” Panin takes on Shinard “Showtime” Bunch over 10 rounds at 147 pounds.

Belarus-born, Los Angeles-based Panin (23-2, 15 KOs) has lost just once in six years, and that was via split decision in March 2025. The 30-year-old heads into his Zuffa Boxing debut having bounced back with a pair of first-round knockouts on the California scene, and now looks to make his mark on the Zuffa Boxing stage.

To do that, he’ll have to defeat Bunch (22-3-1, 1 NC, 18 KOs), who has alternated wins and losses through his last five fights. Despite his rollercoaster form, he heads into Sunday night’s Zuffa Boxing debut on the back of a first-round TKO victory in January. He’ll make a swift turnaround this weekend as he looks to get his career as a Zuffa Boxing fighter off to a winning start.

Joshua Juarez vs Jardae Anderson

The preliminary card will also feature heavyweight action, as Mexico’s Joshua “El Mago” Juarez takes on Jardae “Almighty” Anderson.

Juarez arrives in Las Vegas with an undefeated 14-0 record, with nine wins coming via knockout. The 28-year-old from Laredo, Texas, has stopped each of his last five opponents inside the first two rounds.

He’ll face Davenport, Iowa’s Anderson (11-1, 9 KOs), who has stopped five of his last six, with four of them coming in the first round.

With both men in top finishing form, expect the pair to load up and go for an eye-catching finish to make their mark at the Meta APEX.

Jaycob Ramos vs Ethan Perez

One of two fighters on the card who will be making their second Zuffa Boxing appearance, Jaycob Ramos returns to the Meta APEX hoping the second time will be the charm when he faces Ethan Perez in a six-round featherweight matchup.

“The Raging Bull” (4-1, 1 KO), appeared on Zuffa Boxing 01, where he lost out to Troy Nash on the scorecards after an entertaining six-rounder that made history as the first-ever Zuffa Boxing matchup.

Now, Ramos will step into the Zuffa Boxing ring for the second time in 44 days as he takes on undefeated Perez (8-0, 3 KOs), who racked up four consecutive wins in 2025. The San Antonio native will look to kick off his 2026 with a big win as he faces Ramos in Las Vegas.

Brady Ochoa vs Adrian Serrano

Undefeated Las Vegas lightweight Brady Ochoa will put his unblemished record on the line when he faces fellow unbeaten prospect Adrian Serrano over six rounds at 135 pounds.

Eighteen-year-old Ochoa has already picked up nine professional wins without defeat, and will look to take his young career into double figures when he takes on 21-year-old Serrano (6-0-1, 3 KOs).

Ochoa will step through the ropes having claimed six decision wins in a row, but you can bet he’ll be looking for a knockout when he takes on Serrano, who heads into the bout having stopped each of his last three opponents.

Each fighter represents a significant step up in competition for the other, and both men will step through the ropes looking to keep their undefeated records alive as they look to make a big first impression at the Meta APEX.

Emiliano Alvarado vs Erick Rosado

The opening bout of the night will also feature a boxer making his sophomore appearance inside the Zuffa Boxing ring. 

Mexico’s Emiliano Alvarado impressed at Zuffa Boxing 03 in February when he stopped Devin Gantt in the fourth round of their 122-pound catchweight contest. Now, just 21 days later, Alvarado is back, and will attempt to become the first fighter to win successive bouts under the Zuffa Boxing banner.

He’ll take on the Dominican Republic’s Erick Rosado who is making an even quicker turnaround as he makes his Zuffa Boxing debut just 15 days after his unanimous decision victory over the previously undefeated Christopher Glenn in Washington.

The pair will kick off the night in a six-round featherweight matchup, with Alvarado chasing his second Zuffa Boxing victory, while Rosado looks to announce his arrival with his second straight win over undefeated opposition.
