Raoni Barcelos Hospitalized After Collapse at UFC Vegas 121

UFC veteran Raoni Barcelos collapsed near the fence during the fifth round of his fight against Raul Rosas Jr. at UFC Vegas 121 on Saturday, September 26, 2026. Following the incident, medical personnel entered the Octagon to provide aid before transporting the 39-year-old fighter to a local hospital. Officials have confirmed that Barcelos was awake and conscious upon arrival at the medical facility.

The exact cause of the collapse remains unknown as of now.
