Philadelphia, PA -- (Sports Network) - Philadelphia 76ers center Jason Smith was examined Tuesday afternoon at the Hospital for Special Surgery in New York.

Dr. David Altchek, the attending orthopaedic surgeon in the Sports Medicine and Shoulder Service at the hospital confirmed that the center suffered a torn anterior cruciate ligament in his left knee.

Smith has improved his strength and range of motion in the knee and will continue with therapy and medication before a follow-up visit with Dr. Altchek in early September.

Smith was originally hurt during normal basketball activity earlier this month. No timetable has been set for his return.

The Colorado State product averaged 4.5 points and 3.5 rebounds in 76 games during his rookie campaign last season. He played five games during the recently completed Las Vegas Summer League and averaged 18.6 points with 8.0 rebounds.
