Festus Ezeli is seeking a second opinion on his ailing left knee.

Ezeli is not traveling with the Portland Trail Blazers on their five-game East Coast trip.

Ezeli has yet to appear in a game following a procedure he underwent on his knee in August.

Ezeli appeared to be making progress toward a return last month, when he went through portions of a practice on Oct. 18 and announced afterward that "The Sheriff (was) back in town."

Ezeli subsequently endured swelling and pain with concerns emerging about the long-term health of his knee.
