UFC Fight Night · September 26, 2026
Rosas Jr. vs. Barcelos
Meta Apex · Las Vegas, Nevada
Raul Rosas Jr. gets his first UFC main event at 21 years old against a veteran, No. 13-ranked gatekeeper in Raoni Barcelos, a genuine crossroads fight for a bantamweight prospect the promotion has fast-tracked since he signed as a teenager.
A fight-week reshuffle elevated Norma Dumont vs. Ailin Perez into the co-main event and bumped the originally-booked Rodolfo Vieira vs. Robert Bryczek middleweight bout to the prelims, on a 12-fight card closing out The Ultimate Fighter season 34 with both finals on the same night.
