Cacok won't be available for Wednesday's game against the Raptors due to a left heel contusion.
Cacok hasn't seen any action for San Antonio since Feb. 26, so he presumably picked up the injury during his most recent appearance for the G League's Austin Spurs on Tuesday. The 6-foot-7 big man wasn't in line to be a part of head coach Gregg Popovich's rotation Wednesday even if he was fully healthy.
