Barcelos says medical testing has yet to determine why he lost
consciousness during his
Ultimate Fighting Championship headliner against Raul Rosas
Jr.
Barcelos faced Rosas Jr. in the main event of
UFC Vegas 121 last month. The Brazilian led on the judges’
scorecards entering the fifth round but lost consciousness during a
grappling exchange against the fence. Rosas Jr. was awarded a
technical knockout victory, and the 39-year-old Barcelos was
transported to a Level 1 trauma center.

Raoni Barcelos undergoes medical tests after losing
consciousness against Raul Rosas Jr. at UFC Vegas 121
Barcelos said he is undergoing tests in Las Vegas to determine what
happened. He hopes to continue fighting but has not ruled out
retirement.
“Unfortunately, we don’t know what happened,” Barcelos told MMA
Fighting. “It was a sudden illness. I fell ill and I felt my whole
body really starting to go numb. After that, I don’t remember
anything. I only remember [arriving] in the ambulance, asking my
father what happened, and him trying to explain it as best as he
could. It really was an unfortunate [circumstance]. I got sick and
to this day we still don’t understand. I’m undergoing a battery of
tests here in [Las] Vegas. I had another on Monday and we’re
waiting for a good result. The doctor hasn’t released the results
yet and everything is being kept confidential. But I feel better
every day.”
Barcelos (22-6) entered the bout on a five-fight winning streak. He
has competed in the UFC since 2018, compiling an 11-5 promotional
record with victories over Said
Nurmagomedov, Cody
Garbrandt and Payton
Talbott.
