The Spurs said Thursday that the swelling in Parker's ankle was minimal after being carried off the court Wednesday night in a win over Atlanta. No structural damage was found.
Parker won't play Friday against Memphis and will also likely sit Sunday's game against Denver. No timetable for his return has been set.
Parker has been troubled by the same foot all season. He missed four games earlier because of another ankle sprain and has been bothered by plantar fascitis.
The injuries have cost Parker the quickness he had last season, when he was an All-Star and led the Spurs in scoring.
