Memphis is in a grueling stretch of its schedule, playing nine out of 11 games on the road. The game Monday night at Oklahoma City was also the start of a back-to-back-to-back set for the Grizzlies.
For the Thunder, reserve guard Daequan Cook was available to play again after missing the previous six games with a sprained ligament in his right knee.
