Guard Jarrett Jack will undergo surgery to remove scar tissue and loose particles from his left ankle Friday in Los Angeles, it was announced by the team Thursday.

“Jarrett played the entire season on an ankle that he badly sprained prior to the draft last year,” said Trail Blazers General Manager John Nash. “It never healed fully and he should be physically superior this coming season as a result of this procedure.”

Recovery time is expected at 8-10 weeks, and Jack will likely not participate in the Las Vegas Summer League in early July.

Posting averages of 6.7 ppg, 2.0 rpg and 2.8 apg during the 2005-06 season, Jack became the first Portland rookie in 10 years to log 1,500-plus minutes in his inaugural NBA campaign while leading the team with 79 appearances.
