Pregame notes

Couple of updates before the Lakers take on the Atlanta Hawks tonight:

Andrew Bynum shot baskets during the morning shootaround, but Lakers coach Phil Jackson said the 7-foot center probably won't start an exercise program until March. Bynum has been sidelined since tearing the MCL in his right knee Jan. 31. He probably will be out until April. ... Sasha Vujacic said his sprained left ankle is sound again after he took a Mexican vacation over the All-Star break. ... Adam Morrison and Shannon Brown were on the Lakers' active roster for the first time together since they were acquired from the Charlotte Bobcats for Vladimir Radmanovic on Feb. 7.
