It’s been a bad week for Niners fans. On Monday, a group of San Francisco fans battered a Vikings fan after the game; four suspects were arrested over the weekend on felony charges. On Sunday, a group of 49ers fans reportedly started trouble in a Los Angeles Buffalo Wild Wings, and ended up on the wrong end of a walloping.

Here’s the video, taken by Facebook user Dave Amaro, from the incident at the Stonewood Center in Downey, CA:

And here’s what Amaro wrote in the caption for the video:

Niner fans starting shit, get rocked outside B-Dubs in Downey (sore losers)

Background edit:

The guys getting beat up started problems inside. They wanted to beat up a Steelers. The Steelers fan walked away. The rude 49er fans started talking shit to everyone. They messed with the wrong group when they went outside and got beat up. The Guy in in red at :09 second was the one that started everything

When the group of San Francisco fans got outside, it looks like they ran into a group of Giants fans (you can make out a throwback Simms jersey, and a... Mathias Kiwanuka shirt?). Police were called to the scene, but no injuries were reported and no charges were filed. According to NBC 4 Los Angeles, police continue to “investigate the incident, including interviewing Buffalo Wild Wings workers.”
