Raul Rosas Jr. won his first UFC main event Saturday at the Meta APEX in Las Vegas, stopping Raoni Barcelos by TKO at 1:38 of round five — then spent the night asking fans to pray after Barcelos was stretchered out.

ESPN and UFC said Rosas (13-1) trailed on all three scorecards entering the final round of the bantamweight bout before a fence clinch and slam left Barcelos unconscious. Referee Herb Dean waved it off. The UFC said Barcelos was taken to a Level 1 trauma center, received a CT scan, and was stable, alert, and responsive with full movement while remaining under observation. Coach Davi Ramos also posted that Barcelos was doing well and urged fans to stay calm. Sherdog described the finish as bizarre because the takedown looked relatively routine until Barcelos did not get up.

Rosas, once the youngest fighter to sign with the UFC, extended a six-fight winning streak and did not celebrate in the cage, calling Barcelos a warrior. The 17-year age gap with 39-year-old Barcelos was the widest in a UFC main event. Sunday MMA search traffic stayed on the result and the hospital update more than on immediate title-talk hype, even as Rosas remains a ranked bantamweight prospect on a heater. Promotional partners streamed the Apex card on Paramount+ in the United States, keeping the medical aftermath in front of a wide MMA audience overnight.

Accounts agree on the round-five TKO, the stretcher exit, and the UFC's stable-and-alert update. They differ mainly on how to grade the finish quality versus the medical scare that defined the night.
