PORTLAND -
The Portland Trail Blazers say that a procedure to clear debris out of center Greg Oden's left knee resulted in another microfracture surgery.
Oden had the surgery on Monday in Vail, Colo. Although it was originally expected to be an arthroscopic procedure to clean out the 7-footer's knee, the surgeon determined there was additional damage.
The former No.1 pick in the 2007 NBA draft has now had two microfracture surgeries on his left knee, and one on his right. He has also undergone surgery for a fractured left kneecap.
The Blazers say Oden will not play this season.
Oden starred at Lawrence North High School in Indianapolis.
