The Portland Trail Blazers announced that third-year forward Noah Vonleh underwent a successful procedure to remove a bone fragment from his right thigh on Wednesday.

Dr. Evan Ellis performed the procedure at Rebound in Vancouver, Washington. The Blazers say Vonleh will need 3-4 weeks to recover.

Vonleh, 21, averaged 3.6 points and 3.9 rebounds in 78 games, including 56 starts, with the Blazers last season.

The Blazers open training camp at the end of September. Their regular season opener is on Oct. 25 against the Utah Jazz.
