Tiger Woods is no longer on crutches, but he says in his monthly newsletter that he does not know when he will return to the PGA Tour.
The world's top-ranked golfer had arthroscopic surgery on his left knee April 15th, just two days after he finished three shots behind Trevor Immelman in the Masters. It was the second time in five years Woods had surgery on his left knee.
Woods used the crutches last week in Las Vegas at "Tiger Jam XI," a charity concert that raised more than $1.5 million for his foundation, and now, he is in a knee brace. He says he's "a little stir crazy" and hopes to start rehabilitation soon.
Woods will not defend his title next week at the Wachovia Championship, and he also will miss The Players Championship for the first time in his career. His hope was to return for the Memorial, which starts May 29th.
The U.S. Open will be played June 12-15 at Torrey Pines, a course where Woods has won six times as a pro.
