Woods said on his website today that he had surgery Monday in Utah for a pinched nerve that had been hurting him for several months. He withdrew during the final round of the Honda Classic and skipped his title defense at the Arnold Palmer Invitational.
The procedure was successful, but Woods will be unable to play in the Masters Tournament, which is next week in Augusta, instead requiring rest and rehabilitation for the next several weeks.
"After attempting to get ready for the Masters, and failing to make the necessary progress, I decided, in consultation with my doctors, to have this procedure done," Woods said on his website.
It will be the first Masters the four-time champion at Augusta National will miss since he first played as an amateur in 1995, says USA Today.
The world's No. 1 player says he hopes to be able to return this summer.
