Raul Rosas Jr. Reflects on Chilling UFC Vegas 121 Finish Against Raoni Barcelos: 'I Didn’t Know if He Died'

At UFC Vegas 121, Raul Rosas Jr., 21, secured his first UFC main event victory by knocking out veteran Raoni Barcelos in the fifth round. What was officially called a slam knockout quickly turned into a frightening moment as Barcelos appeared to lose consciousness mid-takedown before hitting the mat. The 39-year-old Barcelos was stretchered out and taken to the hospital. The UFC later confirmed he was stable, alert, responsive, and moving fully.

Rosas’s Initial Reaction

"For a second, I didn’t know if he died, to be honest," Rosas told Uncrowned during Monday’s Ariel Helwani Show. "But when I calmed myself down and checked if he was breathing, seeing his chest rise and fall, I thought, OK, he’s not dead for sure."

He added that while relief came with confirming Barcelos was alive, he spent time praying that Barcelos would wake up and return safely to his family.

The Fight and Its Impact

The intense five-round battle between bantamweight contenders ended with shock and concern overshadowing Rosas’s sixth consecutive UFC win. Rosas admitted the scary finish dampened the celebration but expressed respect for Barcelos’s effort.

"It was scary because of that, but yes, I was happy with my performance on the side," Rosas said. "He’ll probably be sad about the result, but I’m pretty sure he’ll be happy about the fight because we both went all out and wanted the win."

Rosas has reached out to Barcelos but has yet to receive a reply. Reports indicate Barcelos regained consciousness the night of the fight and was able to move his limbs. Both Barcelos and his coaches have since released statements.

What Caused the Sudden End?

Rosas remains puzzled over how the fight concluded so abruptly. He insists he did not hit Barcelos’s head hard enough to cause unconsciousness, a claim supported by video review.

"From my side, I didn’t hit his head," Rosas explained. "I watched the replay too. I want to see if he remembers what happened because he knows better than anyone."

He described the fourth round as physically exhausting, noting Barcelos had him in a tight submission hold while gasping for air. Both fighters showed signs of fatigue going into the final round.

"He was squeezing the whole time, but he wasn’t choking me," Rosas said. "When he returned to his corner after the fourth, he looked wobbly from tiredness. I felt it too but managed to rest more on the floor."

Heading into round five, Rosas pushed the pace, sensing Barcelos's body was shutting down from exhaustion. He recalled landing a light punch before attempting the takedown that ended the fight.

"I don’t know if that punch caused it," Rosas said. "When I grabbed him, he felt weak, like his body was done. I felt confident going for the legs and knew I had won. After taking him down, I just knew I would finish him there."

Reflecting on the fact Barcelos seemed unconscious before hitting the mat, Rosas expressed surprise and sympathy.

"Now that I see he was out before the takedown, I think maybe that’s why he felt so weak," he said.

Judging and Pressure

Barcelos was ahead on the scorecards, with all three judges giving him a clear lead before the stoppage. One judge even scored the fourth round 10-8 in Barcelos’s favor.

Rosas acknowledged feeling pressure after the strong fourth round from Barcelos but thought differently about the fight’s flow in his mind.

"I was down going into the fifth, but my mind had a different score," Rosas said. "I thought Round 1 was mine, Round 2 could have gone either way, and 3 and 4 were his rounds, so maybe it was tied 2-2. Still, I figured if it went to the judges, he’d probably win because of the dominant fourth."

Knowing this, Rosas felt he had to end the fight decisively in round five to avoid doubt.

"I didn’t want uncertainty about winning or losing, so I had to go for the finish," he said.

Rosas’s Rising UFC Career

This win moves Rosas to 7-1 inside the UFC and 13-1 overall. It marks his second victory against ranked opponents since joining the promotion in late 2018 at just 18 years old.
