This is now the second time he has suffered from a ruptured achilles. In 2008 he tore his right one and this time he has torn his left. With his back also having had over 10 surgeries as well one really has to wonder if he tries to attempt a PGA comeback.
With the TGL launching he could move to playing at his teams events and then play in the Masters or another huge tournament. I cant see him returning to regular PGA play though.
