L.A. Rams players weren't the only ones taking a beating from Dallas on Sunday ... their fans were, too -- with one dude getting KO'd by a Cowboys fan during a parking lot brawl.
The SoFi Stadium parking lot brawl was caught on video as the Rams were losing to "America's team."
The video shows several people in Rams and Cowboys jerseys going at it as a few people attempted to keep the peace.
But, nobody listened ... and then, out of nowhere, a guy in a #88 jersey (CeeDee Lamb, Dez Bryant, Michael Irvin, Drew Pearson??) -- throws a superman punch at a fan wearing a Cooper Kupp jersey, knocking him to the ground.

The Cowboys fan didn't stop there ... the guy continued to punch the Rams fan in the face until witnesses broke things up.
The Kupp fan eventually gets up but falls back to the asphalt ... obviously shaken up from the blows to the head.
But, he wasn't the only one injured ... nearby there's another guy laid out on the ground.
It's not the only fight that went down during the Cowboys-Rams game on Sunday. Inside SoFi, a fan wearing a Matthew Stafford jersey was knocked on his ass by a guy in an Ezekiel Elliott jersey.
