More surgery for Oden

The Portland Trail Blazers announced Monday that center Greg Oden will miss the remainder of the season after having microfracture surgery on his left knee.

"Initially, Greg was undergoing a procedure similar to the one he had a couple of weeks ago to have debris cleared from his right knee," said acting general manager Chad Buchanan. "However, once the doctors were inside Greg's left knee, they unfortunately found articular surface damage and determined microfracture was necessary."

This was the fifth surgery the 7-foot Oden has endured since he was taken by the Blazers with the first pick in the 2007 draft.

Oden has not appeared in an NBA contest since the 2009-10 season.
