Exact same thing happened to me in a league in Canada and the guy was given a 4 game ban. The force of the kick snapped my teeth and lodged them in the roof of my mouth and the fallout from the lack of punishment resulted in the league disintegrating.
I'm not sure what the fuss is - locking onto the ball and holding the player up has been a tactic for years. It is a great way to turnover ball and it forces the attacking player to be conscious of their body position in the tackle. »
I think that's pretty good and could of even been longer - the action falls into the category of undue care for a player in a prone position ala Frans Steyn's tip tackle on Cruden that earned him 5 weeks. One difference I see here that may have called for a longer ban is that in Steyn's case, it was in the heat of the moment with milliseconds to react. This action was post-tackle and not even play-related.
