NFL Fan Brawls Break Out In Stadiums On Both Coasts During Week 3

As the San Francisco 49ers and Arizona Cardinals battled on the field, fans of both teams fought in the stands at University of Phoenix Stadium in Glendale, Arizona.

Several 49ers and Cardinals fans were recorded throwing punches during a violent brawl that spilled down the steps at the game on Sunday. One of the fans appeared to be bloodied as stadium staff had difficulty restoring order.

On the other side of the country, a handful of fans wearing Eagles jerseys were caught on camera fighting each other in the stands at Lincoln Financial Field during Philadelphia's game against Washington.
