● The short answer
Raul Rosas Jr. stopped Raoni Barcelos with a fifth-round TKO at UFC Vegas 121, held September 26, 2026, at the UFC Apex in Enterprise, Nevada: his first main event and sixth straight win, improving to 13-1. The finish came after Rosas slammed Barcelos to the mat, and it turned frightening. Barcelos briefly lost consciousness and was stretchered out and hospitalized, dropping to 22-6. His coach later gave a positive update, saying he was stable. In the co-main event, Ailin Perez won a contested unanimous decision (29-28 on all three cards) over Norma Dumont, a result Dumont publicly disputed afterward.
A card with no title on the line still found real stakes, and a scare nobody wanted. Raul Rosas Jr. stopped Raoni Barcelos in the fifth round of his first UFC main event on September 26 at the UFC Apex in Enterprise, Nevada, then spent his post-fight interview asking fans to pray for the man he'd just finished.
The finish
Rosas, 21, had already dropped Barcelos in the opening minutes with a slam before working him down over four more rounds. The fifth-round stoppage, Rosas's first knockout finish since November 2023, came after another takedown left Barcelos unable to intelligently defend himself. He briefly lost consciousness in the cage, was stretchered out, and taken to hospital. It was, by several ringside accounts, one of the more frightening scenes the promotion has had this year.
The update since has been the right kind of boring. Barcelos's coach told reporters the next day that "everyone can relax": he is stable and recovering. Scorecards later showed the fight had been competitive on the feet before the finish; Barcelos was, on paper, minutes from a win.

Where it leaves Rosas
Sixth straight win, first main event, first finish in nearly two years: 13-1 is a real bantamweight résumé at 21 years old. His only loss remains a 2023 decision to Christian Rodriguez, his second pro UFC bout. A main event on this kind of stage, even one that ended uncomfortably, is the clearest signal yet that the bantamweight division has a genuine prospect on its hands.
The rest of the card
Ailin Perez took a unanimous decision (29-28 across the board) over Norma Dumont in a co-main event that Dumont has since called one of the worst decisions she's seen, a dispute that will likely follow both into their next bookings. Elsewhere, Luis Hernandez needed one round to submit Sedriques Dumas, and Ilimbek Akylbek won by disqualification after Mahammadali Osmanli landed an illegal knee.
The record says TKO5. The story of the night is a fighter who finished the job, then immediately asked the room to worry about someone else.
