Oh, that is sad yes. Really though, with the ridiculous amounts of drinking, and throat cancer on top of that it's a miracle he is alive at all.
Mind you, I think one could probably call headbutting an official at a world championship "getting out of hand". I can't remember much worse incidents than that in the game.
Andy Hicks is the resident professional at my club, i've met him a few times, but never played him, that would be truly pointless. He is not a high ranked player, but he made it to the semis of the British Open and second round of the world championship in 2006 where he distinguished himself by starting a fight with Quentin Hann, and walking out on Ronnie O'Sullivan while he was in the middle of a shot.
The press crucified O'Sullivan instead though, he was their favourite whipping boy that year.
