Vassell is questionable for Tuesday's game against the Thunder with left knee soreness, independent NBA writer Matthew Tynan reports.
Vassell missed the second leg of San Antonio's back-to-back Saturday against Dallas for rest purposes, so it's not a good sign that he's now dealing with left knee soreness. The Spurs usually tread very carefully, and Vassell's late addition to the injury report is a worrying sign. If he can't go, players such as Stephon Castle, Tre Jones and Malaki Branham could be more involved.
