Add Vijay Singh to the list of golfers with knee injuries.
First Tiger Woods went down in June after winning the U.S. Open on one leg, then Adam Scott dislocated his knee cap for the sixth time while running on a beach. Now Singh will have surgery for a torn meniscus, according to the Honolulu Star-Bulletin. Singh, 45, will tough it out this week at the Mercedes on the hilly Plantation course, but he has withdrawn from next week's Sony Open and will be out five weeks. It has to be frustrating for a range rat like Singh, who went a whole month in the off-season without touching a club to allow tendinitis in his left arm to heal. It looked like he would come into 2009 in prime condition. He easily won the FedEx Cup in October, and beat a star-studded field at Tiger's charity event in December.UPDATE: Singh said on Wednesday he hopes to only be out three weeks. If everything goes well with his surgery, he will return to the Tour at the AT&T at Pebble Beach next month."If I can come out then, then it will be okay, but I don't know what the doctor is going to tell me," Singh said. "He said my legs are really strong, which is a big advantage, having an operation like that. So I should be all right."
