MEMPHIS, Tenn. (AP) — Lakers center Dwight Howard has aggravated his right shoulder injury against the Memphis Grizzlies and is out for the second half.
Howard was 0-for-4 from the floor and had two points before he flexed his right shoulder and headed to the locker room with 2:21 left in the second quarter.
He did not return for the start of the second half. Lakers officials say Howard aggravated the shoulder that has a torn labrum and already had him listed as probable for the game.
Howard had two rebounds and a blocked shot in just over 14 minutes.
