Vassell (groin) is listed as doubtful for Wednesday's game versus the Knicks, Paul Garcia of ProjectSpurs.com reports.
Vassell will likely miss his third straight game Wednesday due to a left adductor strain he suffered Nov. 2 at Phoenix. Malaki Branham should pick up another start in place of Vassell, whom head coach Gregg Popovich said is being considered day-to-day following a recent MRI.
