The Miami Dolphins hosted the San Francisco 49ers on Sunday. Some people made the mistake of showing up in 49ers jerseys and a bunch of Dolphins fans fought them while a woman held a small, sleeping child. To help escalate things, one Dolphins fan punched a Steelers fan with the 49ers fans in the face. There are guys jumping over entire rows of seats. Grandparents eating haymakers. Just an a tremendous amount of NFL fan violence packed into one clip. Really makes you remember why you should never actually attend one of these games in person.
