Intentional all the way. You can see he juts out his shoulder just as the player walks by him. I don't know what happened in that play but I'm guessing some sort of hit out of bounds?
I wish the fans would have pegged one of their own players. How the hell did they not throw people out? Commanders fans get ejected for a friggin' sign but these jackholes are throwing things which could injure someone.
Just wish they would use Philly as a nuclear testing site.
