Norma Dumont VS Ailín Pérez

Ailín Pérez defeated Norma Dumont by unanimous decision in a women's bantamweight bout at UFC Fight Night: Rosas Jr. vs. Barcelos on September 26, 2026 in Las Vegas. All three judges scored it 29-28 for Pérez across three full rounds. Pérez set the tone early with a takedown late in Round 1, working punches and shoulder strikes from top position to win the opening frame; her wrestling and clinch control proved the recurring difference on the cards. Dumont found more success in the striking exchanges in Round 2 and made the fight competitive, but could not overcome Pérez's grappling advantage over the course of three rounds.

Ranked second in the women's bantamweight division, Norma Dumont aims to bounce back from the loss that snapped her six-fight winning streak against Ailín Pérez, herself riding a six-fight winning run after defeating Macy Chiasson. This is effectively a number-one contender conversation dressed as a main card fight, with the winner positioning herself as the clearest next challenger for the title. Both Argentinian-Brazilian rivals want the same belt, and the bad blood from months of public back-and-forth adds edge to an already high-stakes contest.
