Parker, who missed Friday's loss to the Pelicans in New Orleans, is reportedly dealing with a hamstring strain. He has missed nine of the Spurs' last 12 games.
Over 21 games this season, Parker, 32, is averaging 16.2 points and 5.2 assists.
“Every time he thinks it’s back, he feels something,” Popovich said, according to the Express-News. “He felt it at the end of the Clipper game. He gave it a run (Thursday). You can’t have him doing that so we’re going to sit him. Give it time and if we err, it’s on the conservative side. It keeps coming back and that’s not good, so we’re just going to sit him out for a while.”
Parker is not the only key contributor to miss time for the Spurs this season. Small forward Kawhi Leonard is sidelined with a hand injury and center Tiago Splitter sat out games because of a calf issue.
The Spurs (18-13) will host the Houston Rockets on Sunday.
