San Antonio Spurs forward Tim Duncan plans to return to the lineup Saturday against Washington.

Duncan has missed the last four games with a sore left knee.

"I feel good," Duncan said after practice Thursday. "I probably could have played Wednesday night (against Charlotte). Probably best I didn't, just give it a couple of extra days to get back to 100 percent."

The 36-year-old Duncan is averaging 17.5 points and 9.8 rebounds per game this season.

The Spurs have won nine straight and sit first in the Southwest Division with a 37-11 record.
