Match Previews
Cruiserweight World Championship: Jai Opetaia vs. Brandon Glanton
Jai Opetaia is the real deal. The 30-year-old Australian southpaw enters at 29-0 with 23 knockouts, standing 6'3" with a 76-inch reach. He holds the IBF and Ring Magazine cruiserweight titles and has stopped four straight opponents, including wins over David Nyika, Claudio Squeo, and Huseyin Cinkara throughout 2025. There is a legitimate argument to be made that Opetaia is the best cruiserweight on the planet right now.
Glanton, known as "Bulletproof," is no pushover. The 33-year-old Atlanta native carries an 85% knockout rate and a 21-3 record with 18 stoppages. He has been knocking on the door of a world title for years, and this is unquestionably the biggest stage of his career. Glanton's power makes him dangerous to anyone in the division.
The main storyline heading into Sunday is whether Opetaia's IBF belt will also be at stake. Zuffa's promotional materials list only the Zuffa Boxing Cruiserweight World Championship, and neither the promotion nor the IBF has officially confirmed the status of the IBF title as of fight week. Regardless, Opetaia enters as a heavy favorite and looks to make history as Zuffa Boxing's first world champion.

Welterweight Co-Main: Ricardo Salas vs. Jesus Saracho
An all-Mexican welterweight matchup rounds out the main card in a 10-round contest. Both Salas and Saracho carry championship aspirations and should make for an entertaining co-main event for the growing Zuffa platform.
Featherweight Main Card Opener: Adan Palma vs. Pablo Rubio Jr.
Mexico's Adan Palma squares off against American Pablo Rubio Jr. in an 8-round featherweight bout to open main card action. This is the kind of competitive matchmaking at 126 lbs. that could produce a breakout performance for either fighter.
