Nothing SHOULD happen to them, unless they are planning to plead guilty.
Im sorry - but due process, and innocent until proven guilty still stand here. I don't care how much of a ratbag the player is - so much bad could come of this, if they pursue down this track.
I agree that the NRL has a HORRIBLE track record of how they handle player and societal indiscretion. If they ban a player, who is yet to be found guilty of anything, then they are not only playing lawmaker, but setting an absolute dangerous precedent.
