In this June 15, file photo, Tiger Woods holds on to his left knee after teeing off on the second hole during the fourth round of the US Open championship at Torrey Pines Golf Course in San Diego. Woods will miss the rest of the season because of a left knee that will require more surgery, a person with knowledge of the decision said Wednesday.

Tiger Woods will miss the rest of the season because of surgery to repair a torn ligament in his left knee, an injury he has been dealing with the last 10 months despite winning nine of 12 tournaments.

Woods also said he suffered a double stress fracture of his left tibia while preparing to return to the PGA Tour last month, which forced him to miss the Memorial and was the source of his pain at Torrey Pines when he won the U.S. Open.

He had arthroscopic surgery April 15 to clean out cartilage in his left knee, bypassing ACL surgery with hopes it could get him through the 2008 season. But going 91 holes for his 14th career major made it impossible to play any longer.

"Now, it is clear that the right thing to do is to listen to my doctors, follow through with this surgery and focus my attention on rehabilitating my knee," Woods said.

Woods was last seen in public late Monday afternoon walking with a pronounced limp across Torrey Pines toward the parking lot, the U.S. Open trophy in his arms. Upcoming surgery makes his 14th major title even more staggering — despite the stress fractures, he managed to win a U.S. Open that required 91 holes over five days.

Woods played only seven times worldwide this year and won five of them. He will miss a major championship for the first time in his career and will not be available for the Ryder Cup in September.
