The Portland Trail Blazers announced that guard Brandon Roy underwent arthroscopic surgery today to repair a partial tear in the meniscus of his left knee. Roy is expected to be out 4-8 weeks.

“We are looking forward to Brandon making a full recovery and expect him to be ready for the start of the regular season,” said Trail Blazers General Manager Kevin Pritchard.

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