It may only be preseason, but the fan fights are already in regular-season form.

A video surfaced on Sunday of a group of Raiders and Rams fans getting into a fight during Saturday’s preseason game at L.A. Memorial Coliseum.

The fight gets wild quickly. Two male fans brawl over a railing, a female fan falls down and another female fan throws a beer cup at another fan. It’s certainly a sight to see — especially considering that, again, this is only the preseason.

Watch exactly how this crazy fight unfolds below:

If it’s this rowdy during preseason, just imagine what Raiders fans will get into when the regular season gets underway.

Coincidentally, the Raiders and Rams play again in the regular-season opener on Sept. 10 on Monday Night Football. Only that time, it will in Oakland. So watch out, visiting Rams fans.
