Forward Kawhi Leonard, who was a starter in the San Antonio Spurs' first nine games, will be sidelined 10-14 days because of quadriceps tendinitis in his left knee, the team announced Friday.
An MRI exam performed Friday confirmed the diagnosis.
Leonard will not be with the Spurs for their six-game road trip, which begins Nov. 21 in Boston.
Leonard, a second-year player and one of the team's best defensive players, played 33 minutes in Thursday night's loss to the Knicks. He had 16 points, nine rebounds, and two steals in that game while helping to limit the Knicks' Carmelo Anthony to nine points on 3-of-12 shooting.
Leonard is averaging 13.2 points and 6.8 rebounds this season.
