the bad days."

Questions about the 14-time major champion have shifted from if he will win another major to if he will play another major.

The statement on his website said Woods' bottom disc in his lower back has severely narrowed, causing sciatica and severe pain in his back and legs. Woods opted for a fourth surgery when more conservative therapy, such as rest and injections, failed to solve anything.

"He had consulted with a number of top people that had recommended this was the way to go if he wanted a clear and final path," Steinberg said. "Everything he had done in the past was a temporary fix, so to speak. At that point, they thought there were other alternatives than fusion."

Steinberg said they were advised fusion surgery was thebest option if Woods wanted an active lifestyle and was willing to sit out the rest of the season.

"He should be better than he's been in the past five years," Steinberg said. "He's pretty encouraged."

The surgery was described as "anterior lumbar interbody fusion" at the L-5 and S-1 of his spine. It was performed by Richard Guyer of the institute's Center for Disc Replacement, and involved removing the damaged disc and lifting the collapsed disc space to normal levels.

"After he recovers from surgery, he will gradually begin his rehabilitation until he is completely healed," Guyer said on the website. "Once that's accomplished, his workouts will be geared to allowing him to return to competitive golf."

Guyer said the bottom of the spine is the best place for single-level fusion
