A Steelers Fan Fight That Features an Epic Headbutt

Two Pittsburgh Steelers fans were arguing toe-to-toe in the stands on Sunday when one of them headbutted the other, knocking him out of the picture. 

Other fans try to get in the middle . . . but then the headbutted guy comes back for more, and this time the dude punches him several times.  The entire area turns into a small scrum until security arrives.
