FILE - In this May 12, 2011 file photo, Tiger Woods bends his knee after his second shot on the ninth hole before withdrawing in the first round of The Players Championship golf tournament in Ponte Vedra Beach, Fla. Injuries to his left knee and Achilles' are bad enough that Woods decided Tuesday, June 7, 2011, to skip the U.S. Open for the first time since 1994. The Masters is now the only major he has never missed as a pro. (AP Photo/Chris O'Meara, File)
