I can't remember what game it was, it think it was against Temple back in the late '80s or '90s. But I had never seen players from an opposing football team jump into the stands and start fighting with the home fans. They were swinging helmets! If I remember right, there was a late hit out of bounds on a Syracuse player. The opposing player was ejected, then flipped off the Dome folks while walking to his sideline. The the SU fans behind the visitor's bench started throwing stuff at them, then the fights started between the players and fans. The field was cleared while the Dome when crazy. Pretty wild. When they resumed the game after 15-30 minutes, SU was given two 15 yard unsportsmanlike penalties. Never forget it.
