Lakers' center Andrew Bynum injured his left knee and ankle in the third quarter of Sunday's game against the Grizzlies and had to be assisted off the floor.

With just under nine minutes left in the third, Bynum went up for a rebound. As he came down, his left foot landed on top of teammate Lamar Odom's foot, causing his left knee and ankle to turn awkwardly.

Bynum lay on the floor for a short while before leaving the court with the help of team's training staff. He will not return and is scheduled to undergo an MRI on Monday.
