Bynum update

Andrew Bynum has started workouts on a stationary bicycle and an elliptical trainer this week, the first steps in his rehabilitation and recovery from a torn medial collateral ligament suffered Jan. 31 against the Memphis Grizzlies. The Lakers expect the 7-foot Bynum to be sidelined until at least April. Coach Phil Jackson said recently he doesn't expect Bynum to be ready to resume basketball drills until some time in March.
