Washington  - Tiger Woods, fresh off his thrilling US Open victory, announced Wednesday that will miss the rest of season to undergo surgery on his left knee and rehabilitation for a stress fracture in his leg.

Woods was at times in pain during the US Open, which he won Monday in a tie breaker that extended the tournament to 91 holes. Woods won by one stroke over upstart Rocco Mediate, who bogeyed on the final, sudden death hole.

"I know much was made of my knee throughout the last week, and it was important to me that I disclose my condition publicly at an appropriate time," Woods, 32, said on his website.

"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," he said.

No date has been set for the reconstructive anterior cruciate ligament (ACL) surgery. He will also need time off to rehabilitate a double stress fracture of his left tibia that was discovered last month before the Memorial Tournament.

"While I am obviously disappointed to have to miss the remainder of the season, I have to do the right thing for my long-term health and look forward to returning to competitive golf when my doctors agree that my knee is sufficiently healthy," Woods said.

"My doctors assure me with the proper rehabilitation and training, the knee will be strong and there will be no long-term effects," he said.

Woods hurt his knee in 2007 but continued to play on the PGA circuit. He underwent arthroscopic surgery on the knee earlier this year to clear out cartilage damage resulting from the ACL injury. (dpa)
