The defending FedEx Cup Champion is expected be sidelined for three weeks. He hopes to return to action Feb. 12 for the AT&T Pebble Beach National Pro-Am, where he is scheduled to be paired with his son, Qass.
'The doctor says I'll be on crutches for a few days, and then I'll be OK,' said Singh. 'I don't consider this a big setback or anything. I think the knee will be much stronger in the long run and it is certainly better that it happened now compared to the middle of the season.'
Last week at the Mercedes-Benz Championship, Singh said he hurt the knee in December at Tiger Wood's Chevron World Challenge, which he won. The fifth-ranked player in the world tied for 27th in his 13th appearance at Kapalua.
Singh's 2008 season was very fruitful for the 45 year-old. The Fijian won three tournaments on his way to capturing the FedEx Cup Championship.
