Zuffa Boxing 04 will take place on Sunday March 8th at the Apex in Las Vegas. IBF cruiserweight champion Jai Opetaia will take on Brandon Glanton, but what is at stake will be the inaugural Zuffa Boxing cruiserweight chapionship. [Editor's note: it is unclear if the IBF will continue to recognize the winner of Opetaia-Glanton as its champion]. Opetaia (29-0, 23 KOs) was the first champion signed to Zuffa Boxing. Now the Australian will look add a Zuffa Boxing championship belt to his collection. Standing in his way is hard-hitting Glanton (21-3, 18 KOs), who defeated former light heavyweight champion 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.
Co-feature: Ricardo Salas vs. Jesus Saracho
Two Mexican welterweights take center stage in the co-feature, as Ricardo Salas and Jesus Saracho go head-to-head over ten 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.
Adan Palma vs. Pablo Rubio Jr.
The three-fight main card will kick off with an eight-round featherweight matchup as two undefeated boxers, 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
Vlad Panin vs. Shinard Bunch
Experienced welterweights top the preliminary card lineup as Vlad “Superbad” Panin takes on Shinard “Showtime” Bunch over ten rounds. 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. Bunch (22-3-1, 1 NC, 18 KOs) has alternated wins and losses through his last five fights. Despite his rollercoaster form, he heads into Sunday night on the back of a first-round TKO victory in January.
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 a 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.
Jaycob Ramos vs. Ethan Perez
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
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.
Emiliano Alvarado vs. Erick Rosado
The opening bout of the night will also feature Mexico’s Emiliano Alvarado, who 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 previously undefeated Christopher Glenn in Washington. That means Rosado is hunting his second straight win over undefeated opposition.
