Duncan (knee) is questionable for Wednesday's game against the Suns, Jabari Young of the San Antonio Express-News reports.

EDGE Analysis

Duncan's sore right knee isn't believed to be a serious concern, but with the Suns center tandem of Alex Len and Tyson Chandler not likely to pose much of a threat to the Spurs, there's a chance the aging big man could sit out a third straight game. The Spurs should release an update on Duncan's availability -- or lack thereof -- following their shootaround Wednesday morning.
