Phil Jackson said Lamar Odom might be out for more than a month after spraining his right knee in the first quarter of the Lakers' win at Houston on Tuesday.

"He's going to miss some time," Jackson said. "We would be very happy if he plays in January."

"I don't know exactly when it happened," Odom said. "But I felt like something was really wrong. I have no idea how long it'll be. I've never had anything like this."
