In the 12-round co-main event, co-promoted with Miguel Cotto Promotions, Puerto Rico’s WBA, WBO and Ring Magazine minimumweight world champion Oscar “El Pupilo” Collazo (13-0, 10 KOs) will defend his titles against Mexico’s Jesus “Chiquito” Haro (13-3, 2 KOs). Collazo most recently delivered a devastating knockout victory over Jayson Vayson in September 2025 and returns looking to continue his dominant championship run.
In a title bout co-promoted with Sampson Boxing, undisputed flyweight world champion Gabriela “Sweet Poison” Fundora (17-0, 9 KOs) will defend her throne against WBA Interim World Champion Viviana Ruiz Corredor (10-2, 5 KOs), the Australia-based Venezuelan challenger determined to dethrone boxing’s reigning queen in a 10-round clash.
Recently added to the undercard, Santa Ana’s Alexis “Lex” Rocha (25-2-1, 16 KOs) will face former world champion Joseph “JoJo” Diaz Jr. (34-8-1, 15 KOs), representing South El Monte.
