(August 11, 2025) — Golden Boy announced today a spectacular Unified Championship and Undisputed Championship doubleheader that will feature the sport’s youngest, history-making stars scheduled for Saturday, September 20, live from Fantasy Springs Resort Casino and live on DAZN. In the main event presented in association with Miguel Cotto Promotions, Villalba, Puerto Rico’s unified WBA, WBO, and Ring magazine Minimumweight World Champion Oscar “El Pupilo” Collazo (12-0, 9 KOs) will make history once again when he defends his titles against Jayson “Striker” Vayson (14-1-1, 8 KOs) of Veruela, Agusan del Sur, Philippines.

“I want to thank Golden Boy Promotions and Miguel Cotto Promotions for giving me this opportunity to shine and defend my unified titles on September 20 in Indio, California, against a tough Filipino fighter, Jayson Vayson,” said Oscar Collazo. “All of my fans—Mexicans, Puerto Ricans, Americans, everyone in Southern California—need to show up at Fantasy Springs Resort Casino. It will be the perfect opportunity to dazzle and represent Puerto Rico on such a big platform. We will enter the ring very prepared, with a lot of boxing IQ. We know Vayson is a great fighter and that he will be hungry to dethrone me, but he won’t be able to, because I have worked hard to defend what is mine and represent my island with pride.”
“I want to thank everyone who was able to make this happen,” said Jayson Vayson. “I am a fighter of few words, but I am ready to show the world that I am the best and am deserving of this opportunity. I will shock the world and represent the Philippines with pride!”
In the co-main event presented in association with Sampson Boxing, representing the Coachella Valley, boxing’s youngest undisputed world champion Gabriela “Sweet Poison” Fundora (16-0, 8 KOs) will look to make a third historic defense of her WBA, WBC, WBO, IBF and Ring Magazine World Titles against Ayelén “Piru” Granadino (12-2-4, 1 KO) of Buenos Aires, Argentina. Granadino is no stranger in entering enemy territory and securing a victory, and will try to prove herself against the monstrous Sweet Poison.
“I’m staying 100% focused on defending my belts,” said Gabriela Fundora. “Our immediate teamwork’s intelligent planning and dedicated commitment is the result of our reality.”
“Nothing is free, I have worked very hard to get here,” said Ayelén Granadino. “After I beat Micaela Milagros Lujan in a final elimination for the WBA title, I knew my time had come and I am preparing accordingly. Gabriela Fundora is a great fighter, and I respect her until we get in the ring. I can’t wait to bring the four championship belts back to Argentina with me.”
“We’re back in the Coachella Valley, and this time, Golden Boy is bringing the heat with a barnburner of a card,” said Chairman and CEO Oscar De La Hoya. “This action-packed doubleheader features two history-making Golden Boy fighters, Oscar Collazo and Gabriela Fundora, defending their unified and undisputed world titles against mandatory challengers. The undercard will be stacked with the next generation of Golden Boy stars. You won’t want to miss it.”
Additional details on the preliminary card will be announced in the coming weeks.
Oscar Collazo is making serious noise for the lower weight divisions in boxing. Nicknamed “El Pupilo,” the 28-year-old added to Puerto Rico’s rich boxing history by becoming the fastest fighter from the island to win a world title with only seven professional fights. He secured the victory with a seventh-round knockout over former WBO world minimum champion, Melvin Jerusalem, at Fantasy Springs Casino in May 2023. Since then, he’s had five successful and dominant title defenses. Now, Collazo is set to defend his WBO, WBA and Ring belts once again – this time in a main event showdown against Venezuela’s veteran Ronald Chacón on Sept. 20, 2025. With world titles on the line and national pride at stake, the bout promises fireworks as Collazo looks to continue his reign and Chacón enters the ring for his first world title shot. Through a series of thrilling performances, “El Pupilo” is firmly carving out a path to greatness with the potential to be remembered as one of the greatest fighters of his era, and a legendary figure in Puerto Rican boxing.
Filipino contender Jayson “Striker” Vayson is set to make the biggest ring walk of his career on September 20, when he faces reigning WBO, WBA, and Ring Magazine world champion Oscar Collazo at Fantasy Springs Casino in Indio, CA. The bout will mark Vayson’s highly anticipated U.S. debut and his first shot at world championship glory. Vayson enters the fight riding a four-fight win streak, including an explosive second-round knockout of Japan’s Ryuya Yamanaka to capture the WBO Asia Pacific Light Flyweight title. He previously claimed the WBC Asian Continental belt with a hard-fought split decision victory over India’s Nutlai Lalbiakkima. In February 2022, Vayson challenged Indonesia’s Tibo Monabesa for the WBC International title, dropping Monabesa twice and appearing to control the bout. However, the judges awarded Monabesa a controversial decision win. After reviewing the circumstances – including a panel composed entirely of local officials – the WBC ruled the fight a no-contest and ordered a rematch, which ultimately never occurred. Now holding a record of (14-1-1, 8 KO’s), the 27-year-old from the Philippines is poised to take on one of boxing’s top champions. Ranked No. 3 by the IBF, No. 6 by the WBO, No. 8 by the WBC and No. 11 by the WBA at light flyweight, Vayson will move down to minimumweight for this world title opportunity. With momentum on his side and everything to gain, Vayson enters this world title clash not just as a challenger, but as a dangerous threat ready to shake up the division.
Gabriela Fundora’s journey into boxing came naturally. Growing up in a family with a deep boxing background, she was exposed to the sport from an early age. Training at the Olympic Training Center multiple times as an amateur and securing the 2017 National Championship, her eyes were set on becoming a world champion one day. Her brother, Sebastian Fundora, is the current WBC super welterweight world champion, and her father, Freddy, has been the foundation behind their careers. With dad and older brother in her corner, Gabriela has developed a tough, disciplined mentality that reflects her upbringing. Making her professional debut in 2021, and with her combination of size, athleticism and technical skills, “Sweet Poison” has rapidly become one of the most exciting fighters in women’s boxing. In October 2023, Fundora encountered Arely Mucino, whom she defeated via knockout in the fifth round to become the new IBF flyweight titleholder.
Since becoming world champion, Fundora’s career keeps elevating to the highest levels. In November 2024, she made history by becoming boxing’s youngest four-belt undisputed champion when facing Gabriela Alaniz in dominant fashion. In her latest performance, Fundora delivered a dominant display against IBF mandatory challenger Marilyn Badillo at Frontwave Arena in Oceanside, CA. From the opening bell, she showcased her reach, power and skill, proving there’s a clear gap in levels within the sport. Fundora sealed the victory with a seventh-round knockout, successfully defending her undisputed titles and cementing her role as a leader in a new era of women’s boxing.
Ayelén Granadino has quietly worked her way into world title contention, and now she’s ready for her biggest test yet. The Argentine fighter will face Gabriela Fundora for the undisputed flyweight championship in the co-main event of Collazo vs. Chacón on Sept. 20, 2025. A seasoned competitor, Granadino enters the bout ranked No. 3 by the WBA, No. 6 by the WBO and No. 8 by the IBF – a reflection of her steady climb through the global flyweight ranks. Known for her toughness and assertive approach, she has gone toe-to-toe with some of the top names in women’s boxing and now finds herself on the verge of a career-defining opportunity. As she prepares to face the undefeated and undisputed champion Fundora, Granadino brings both hunger and high-level experience into the ring. With national pride on the line and years of hard work behind her, she’s looking to shock the world and bring the belts back to Argentina.
