Although I'm not a big fan of the guy I do appreciate what he brings to the game I'd be very sad to see him have to cut his career short. However, I haven't seen or heard any rumors to this effect. His camp seem to be making the usual positive sounds about next year so why should we doubt that he won't turn up at the Australian Open and be a contender (if not a serious one after such a long lay off)? Sounds like smoke signals to me.
