Raoni Barcelos was hospitalized after passing out in the final round of his UFC Vegas 121 fight with Raul Rosas Jr.; he lost by knockout. His doctor said Barcelos was lucid and oriented and would stay under observation for several days; the cause was not disclosed.
There was no apparent strike before Barcelos passed out; Rosas Jr. had taken him down and did not follow up with hard punches after realizing Barcelos was unwell. Barcelos was carried out on a stretcher.
Separately, 26-year-old Mexican boxer Arturo Torres died after collapsing in the ring following a seventh-round stoppage of his bout with Gilberto Garcia in Mexicali. Doctors diagnosed a blood clot on his brain; after emergency surgery, he was placed in a medically induced coma.
