Update: Duncan (knee) plans to play in Saturday's game against Washington, the San Antonio Express-News reports.
Recommendation: Duncan has now missed five of the Spurs' past six games due to a sore left knee. Barring a setback, he should make his return, but if not, Boris Diaw and Tiago Splitter will continue to earn additional run in the frontcourt. Continue to consider Duncan day-to-day.
