Terrifying moment at the UFC 324 weigh-in on Friday … when fighter Cameron Smotherman collapsed on stage after stepping off the scale.

The concerning situation played out minutes ago in Las Vegas … when all the fighters on the first-ever Paramount+ card showed up to make weight for Saturday’s fights.

28-year-old Smotherman made weight for his fight against Ricky Turcios at 135.5 pounds … but as he walked toward the exit, he fell face-first to the ground.

Medical staffers on hand rushed to help him … and he was carried away.

UFC commentators Laura Sanko and Daniel Cormier reacted in real time … expressing their shock as the cameras cut from the stage and to their set.

There haven’t been any updates on his status … but we’re sure the organization will provide one as soon as it’s available.

The Smotherman vs. Turcios bout is now off as a result.

Fighters are known to go through insane weight cuts in order to compete in their respective divisions … though it hasn’t been confirmed that’s what sparked Smotherman’s medical scare.

The fighting community has sent a ton of support for the Texas native … with everyone hoping for a speedy recovery.
