Cris Cyborg defeated Ketlen Vieira by unanimous decision in the main event of PFL Tampa on August 22, 2026. With this victory, Cyborg reached a historic milestone as the first woman in mixed martial arts history to secure 30 professional wins. Originally scheduled as a PFL Women’s Featherweight Championship defense, the matchup was altered to a five-round, non-title bout after Vieira missed weight.
Vieira weighed in at 152.2 pounds—well over the 145-pound championship limit—rendering her ineligible to win the belt. However, Cyborg kept the stakes high by promising beforehand to vacate her title if she lost. The match was heavily promoted as the final MMA walk of Cyborg's historic 21-year career. Following her victory, however, Cyborg cast some doubt on immediate retirement. While she intends to spend time with family awaiting the birth of her grandchild, she publicly expressed a continued love for the sport and teased interest in potential future mega-fights, including calling out Kayla Harrison and boxing champion Claressa Shields.
