1) I disagree, his elbow is extended out for the hit so I don't buy that this was accidental.
2) you are supposed to get at least cited, if not suspended, for careless contact to the head, especially when it knocks someone out.
I'm still not buying that this is an accident:

Looks bloody intentional to me, what is that elbow doing extended out? Not 3 players, 2, and Grimes is behind him.
Dog act, covered up by the AFL who play favourites.
If Lynch, or Toby Greene, or lots of others (not Fyfe he does a drive by elbow and nothing to see here) did this they would be out for 4 weeks.
