The Fumble - Some San Francisco 49ers fans took a page out of the Philadelphia Eagle fans' playbook on Sunday, engaging in a brawl with fellow fans in a Levi's Stadium restroom. In the video below, a man in a Frank Gore jersey unloads on a fan wearing a Colin Kaepernick jersey, knocking him out cold. The man in the Gore jersey then starts attacking a second victim with a man in Aldon Smith gear before things ultimately settle down.
