LAS VEGAS, NEVADA - SEPTEMBER 26: Raul Rosas Jr. reacts after a victory against Raoni Barcelos of Brazil in a bantamweight fight during the UFC Fight Night event at Meta APEX on September 26, 2026 in Las Vegas, Nevada. (Photo by Jeff Bottari/Zuffa LLC) Raul Rosas Jr. got the victory in his first ever UFC headliner, but it was not in the way he would’ve liked as Barcelos suffered a medical issue in the fifth round that led to him getting stretchered out of the octagon, leaving fans wondering what happened. While we still don’t have the answer to that question, and at least know Barcelos is recovering, where does Rosas go from his sixth straight win? On an all-new edition of On To the Next One, MMA Fighting’s Mike Heck gives his thoughts on what could be next for the 21-year-old bantamweight contender. Additionally, future matchups are discussed for Ailin Perez following her decision win against Norma Dumont, Luis Hernandez after his breakout debut showing against Sedriques Dumas, along with TUF Finale winners Ilimbek Akylbeck Uulu and Tina Black, and more.
