Raul Rosas Jr. won the UFC Vegas 121 main event on Saturday after taking Raoni Barcelos down in the fifth round. Barcelos went unconscious and limp, then was stretchered out; replays did not make clear what caused him to lose consciousness.
Barcelos rallied after Rosas’ fast start, landing nearly 60 significant strikes in the second round. The third was competitive, and Barcelos dominated much of the fourth, nearly finishing Rosas several times.
After the win, Rosas praised Barcelos’ toughness, asked for a bonus and called for an opponent ranked in the top seven.
