The Portland Trail Blazers announced that all-star guard Brandon Roy will undergo arthroscopic knee surgery today to repair a tear in the meniscus of his left knee.

A Magnetic Resonance Imaging (MRI) taken Tuesday revealed the tear in the meniscus.

Trail Blazers team physician Dr. Don Roberts will perform the surgery at Southwest Washington Regional Surgery Center in Vancouver, Wash.

A timetable for Roy's return will be set following the arthroscopic surgery.
