Rules look good for me...

I did not get to see most of the game, but I saw Clowney limping out. You can't tell by the picture, but from what I was told this was a blatant cheap shot and not much doubt of the intent. I know he is a dumbass but Todd Ellis said it was very close to being a carreer ender. Is any of this true? How would you all rate Clowney and the Cockerdoodles performance so far? I know the game is not over yet.
