The Los Angeles rivalry between the Chargers and Rams has officially begun.

During Wednesday’s joint practice between the two Los Angeles teams, a few fights broke out with the most notable one resulting from a punch thrown by Rams cornerback Trumaine Johnson at Chargers receiver Dontrelle Inman.

Rams cornerback Nickell Robey-Coleman, Chargers receiver Keenan Allen and Chargers quarterback Phillip Rivers also got in on the action, according to the New York Daily News.

"We're definitely building a nice little rivalry with the Rams," Chargers running back Melvin Gordon said, according to the Daily News. "That's what I got out of today."

Fox Sports’ Lisa Lane caught the brawl on video.
