There was quite an altercation during the warmups when both teams inexplicably gathered around the same time in the end zone and started jumping up and down. Then came trash talking, shoving and a few punches. I saw security people, players, coaches and staff get knocked down and I was observing from right in the middle of the field.
The melee continued to midfield, where players were still trying to get back at each other. It was quite a scene and emotions were high. The calmest person was Charlie Weis, who avoided the conflict.
