Terrifying footage shows a fighter shaking uncontrollably after a botched weight cut outside UFC Paris

Ailin Perez appeared terribly uncomfortable as she competed for UFC Paris.

The Argentine fighter will put her three-fight win streak on the line against fellow bantamweight contender Darya Zheleznyakova at the Accor Arena in Paris on Saturday evening.

It is currently unclear whether their clash will take place after Friday's weigh-in.

Zheleznyakova went under the 136-pound bantamweight limit, but Perez missed her mark by half a pound and looked seriously ill on the UFC scale.

Creepy footage shows the usually fun-loving OnlyFans star, known for his twerking parties, looking extremely emotional and unsteady on his feet.

Perez struggled to keep her balance when she was asked to step on the scale.

The 29-year-old stood still enough for UFC officials to take an accurate weight reading, but she could barely lift her arms to flex when her miss was confirmed.

“Fiona” was visibly shaking again and things got worse as she got off the scales and went backstage.

Perez's whole body was shaking and someone stepped in to help her walk.

The 10-2 fighter raised her arm in the air to celebrate what she considered a victory in getting so close to the bantamweight limit after such a difficult weight cut.

UFC fans immediately took to social media to express their concerns about Perez.

One person posted on X: “She doesn't look okay.”

Another said: “This should be canceled wtf.”

A third person asked: “Why does she shake so much at the end?”

Someone else commented: “Man, the weight loss didn't look too good.”

This is the first time Perez has lost weight during her 12-fight professional career.

Paris has not been kind to Perez in the past. In July 2022, she made her UFC debut at Dana White's inaugural show in the city and was submitted by featherweight fighter Stephanie Egger.

The fan favorite has looked great since dropping down a division, but it looks like she may have to think about moving back up to 145 pounds after that scary weight mistake.

Concerns about Perez's well-being have not yet been publicly raised by the UFC.

An update on her fight with Zheleznyakova is believed to be imminent.
