Lakers' center Andrew Bynum will miss another six to ten weeks because of a torn medial collateral ligament in his right knee.

Los Angeles has been without Bynum for seven games already, and will have to rely on Pau Gasol and Lamar Odom if they want to upend the Celtics and Cavaliers for the NBA's best record.

Six weeks from Tuesday would mean Bynum could return as soon as March 31, but ten weeks would push him back to April 28, when the postseason will have already begun.
