The Portland Trail Blazers announced today that center/forward Raef LaFrentz will undergo arthroscopic surgery on Friday, September 26 to repair a tear in the labrum of his right shoulder.

Dr. Neal ElAttrache will perform the surgery at the Kerlan-Jobe Orthopedic Clinic in Los Angeles, Calif.

“I was really hoping to avoid surgery,” said LaFrentz, who sustained the injury during Portland’s game at Seattle on February 22, 2008. “I was hopeful that an off-season regiment of physical therapy and treatment would heal the injury, but unfortunately it’s become clear now that I need to move forward with surgery.”

A timetable for LaFrentz’s return will be set following the arthroscopic surgery.
