UCLA freshman Tony Parker has strained a hamstring and will be out two to four weeks, making his availability questionable for the Bruins' trip to China later this month.
He was injured during a practice for the trip earlier this week.
Parker, a 6-foot-9 center, led Lithonia (Ga.) Miller Grove to four consecutive state titles.
He is one of four freshman in an incoming class that is ranked second nationally by Scout.com.
