More violence in football

By now I am sure you are familiar with the story about the high school football players who attacked an official in the middle of a game last week.  Well...  here is another incident.  For the second week in a row, a San Antonio-area high school is dealing with a player who hit an official in the middle of the game. Here is the video.

Not to be outdone, the pros began their season today and here is a video of Bengals player PacMan Jones ripping an opponent's helmet off and pushing the opponent's head into it after the play was over.

As in the story from last week, the torts issue is the same.  Are these incidents within the scope of the consent to the "inherent risks" of the game?  Is the conduct within the "customs" of the game?

UPDATE (9-14-15):  It sounds like PacMan Jones will not be suspended for his conduct.
