CHICAGO — Results from a second MRI exam on Carlos Boozer's left knee were inconclusive, and the Jazz's All-Star power forward plans to see a specialist in Los Angeles after Christmas.

The appointment in L.A. and a third MRI are scheduled for Dec. 29, which means Boozer will miss at least four more games — and probably more.

He already has missed 17 straight games, including Saturday night's visit with Chicago, due to a strained left quadriceps tendon and bruised kneecap sustained Nov. 19 vs. Milwaukee.

"I don't feel comfortable on it," Boozer said.

Boozer's previous test results were examined by both Jazz orthopedic physician Dr. Lyle Mason and his L.A.-area orthopedist, Dr. Richard Ferkel of the Southern California Orthopedic Institute.

"The biggest concern they had," Boozer said, "was the bone bruise.

"Basically what they said," he added, "was the bone bruise has gotten a little more complicated, a little bit ... bigger."

Best-case scenario, Boozer said, is that he needs only continued treatment and "hopefully (is) able to play soon."

The worst, he suggested, could include arthroscopic surgery.

"It's very frustrating, to say the least," Boozer said. "I want to know what's going on with my knee, so I can get healthy and play.
