Raoni Barcelos is still in the hospital after experiencing a sudden medical issue during his fight against Raul Rosas Jr. at UFC Vegas 121. The incident happened during the fifth round when Barcelos collapsed while the two fighters were on the ground. A doctor who treated him in a Las Vegas hospital described the condition as a "sudden malaise," but the exact cause of the event remains unclear. Barcelos, a veteran in the UFC's featherweight division, was taken off the fight on a stretcher and later received a scan and examination that confirmed he was "stable, alert, and reactive." Combat sports journalist Ariel Helwani reported that Barcelos is conscious, speaking, and able to walk and eat, but the precise nature of his condition and the length of his hospital stay are still unknown. Barcelos's trainer, Davi Ramos, reassured fans that his fighter is "fine" and urged everyone to remain calm. Barcelos himself took to social media in Portuguese, stating he is "very well" and promised to share a video soon. He also thanked fans for their support and said he had kept his promise of delivering a great fight. The fight between Barcelos and Rosas Jr. was the main event of UFC Fight Night 289 and was declared the "Fight of the Night" due to its intensity. In the fifth round, as Rosas Jr. attempted a takedown with a sweep, Barcelos suddenly lost consciousness. Rosas Jr. stopped fighting immediately, and a doctor from the Nevada Athletic Commission checked Barcelos's pulse in the cage shortly after. Although Barcelos was leading on the scorecards at the start of the fifth round, the TKO victory was awarded to Rosas Jr. Barcelos had entered the fight on a five-fight winning streak, with his last loss dating back to August 2023. Rosas Jr., who is now 21, had also been on a five-fight winning streak in the UFC. His victory over Barcelos brought his record to seven wins in eight fights since joining the UFC through the Contender Series in 2022. At 17, Rosas Jr. was the youngest fighter ever signed by the UFC, and the fight marked the largest age gap ever seen in a main event in the organization's history. The UFC is set to host its next numbered event, UFC 332, in Salt Lake City this Saturday. The headline fight will feature Natalia Silva and Wang Cong competing for the vacant women's flyweight title, a belt previously held by Valentina Shevchenko.
