MEMPHIS, Tenn. - Lakers centre Dwight Howard has aggravated his right shoulder injury against the Memphis Grizzlies and is out for the second half.

Howard was 0 of 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.
