UFC fighter who collapsed in frightening moment issues health update after Las Vegas nightmare

Raoni Barcelos has issued an update on his health after collapsing following his knockout defeat to Raul Rosas Jr at UFC Vegas 121.

Barcelos, 39, was brutally knocked out in the fifth round of the contest after a war with his opponent.

As Rosas Jr attempted a takedown, Barcelos appeared to go limp before medics rushed to attend to him.

He was later stretchered out of the cage and travelled to hospital in Vegas, where he reportedly underwent an immediate CT scan.

Thankfully, the fighter has now confirmed that he is “doing great” via a video posted on social media on Monday (September 28).

“Hey, guys, I want to let you all know that I'm doing great and as soon as I can I will send you all a video!" Barcelos wrote.

“Thank you so much for everyone's love and prayers! I promised a great fight and I fulfilled what I promised. Thank you God and everyone who fought together with me inside and out of that cage.”

‘Oh, this is really bad’ – Paul Felder recalls ‘scary’ moment

The update will be positively received by Rosas Jr, fight fans and commentator Paul Felder, who described the incident as the “scariest thing” he’d ever seen at a UFC event.

“His neck was all clinched up, and he was unconscious,” Felder said on Michael Bisping’s Believe You Me podcast.

“And it looked like he was — I thought he had a heart attack, off the bat. Then they came in, and they checked his pulse, which was terrifying to see. I have never seen somebody that was KO’d, where they come in and the first thing they did, the doctor put his fingers right on Raoni’s pulse. I was like, ‘Oh, this is really bad.’

“He was just not getting up, and then I’m thinking, is it a stroke? Is it a heart attack? But if they weren’t doing CPR and his pulse was at least there and present, and he’s breathing, probably not a heart attack.

“That was by far the scariest thing I’ve had — I’ve seen some nasty knockouts, guys out for a while, but they come to. To see somebody where the doctors are checking your pulse, it just kind of really puts it in perspective, too, what this sport is at its roots.”
