"I am extremely disappointed that I won't be playing in the U.S. Open, but it's time for me to listen to my doctors and focus on the future," Woods said in a statement posted on his Web site. "I was hopeful that I could play, but if I did, I risk further damage to my left leg. My knee and Achilles tendon are not fully healed. I hope to be ready for AT&T National, the next two majors and the rest of the year."
Woods hurt his left knee and left Achilles tendon hitting a shot from under a tree during the third round of the Masters. He skipped the Wells Fargo Championship and withdrew after nine holes of the Players Championship.
The 35-year-old former top-ranked player in the world has won 71 PGA Tour events (third-most ever) but hasn't had a victory since before revelations in late 2009 that he had a string of extramarital affairs.
The 111th U.S. Open begins June 16 at Congressional Country Club in Bethesda, Md.
