The Oakland Raiders finally getting a win wasn’t the only crazy thing that went down at Sunday’s football game. Both 49ers & Raiders fans attacked each other in an all-out brawl. The fans brutally go at it so badly that security and police had to intervene. Punches were thrown and beer was spilled along with a little blood, as the O.co Coliseum looked like the Source Awards…Crazy video & footage after the jump!
