WrestleMania Fan Run Over By Golf Cart Carrying Dominik Mysterio

Dominik Mysterio's WWE Intercontinental Championship celebration Sunday night hit a bit of a speed bump ... when a golf cart he was riding in ran over one of his fans.

The wild incident unfolded outside Allegiant Stadium in Las Vegas ... shortly after the wrestler -- who's Rey's son -- won a four-way match for the WWE strap over Finn Balor, Bron Breakker and Penta at Night 2 of WrestleMania 41.

The 28-year-old was cruising around the Raiders' famed building with security -- showing off his new hardware to a cheering crowd -- when, suddenly, a throng of his supporters raced to his ride in an apparent effort to snag a pic.

Check out some video from the scene ... one woman in a red shirt got just a little too close -- and ended up getting clipped by the vehicle.

A man who said he was in the area of the incident claimed he could hear Dom audibly yell "oh s***." It seems the cart's driver did stop to check on her -- though her condition is currently unknown.
