Personally, I don't see anything in it - comparing it to the Billy Slater episode is incorrect. Slater was charged with striking an opponent, I don't think Buderus will see a similar fate.
A panel with rugby league players will see nothing in it, this was an incident that can happen on the football field. Buderus went to pick up the ball as dummy half and unfortunately clipped a player laying around in the play the ball. There no malice or intent, any case he has to answer will be and should be dismissed.
