CHICAGO — Forward Joakim Noah left the Bulls’ game against the Dallas Mavericks on Friday night after separating his left shoulder with just under 10 minutes to play in the second quarter.

Noah was in his fourth game back after returning from a nine-game absence because of an injury to the same shoulder.

The Bulls said Noah wouldn't return to the game.

Noah got tangled up with the Mavericks' JaVale McGee under the basket, yelled in pain while holding his shoulder, and immediately ran off the court and to the locker room.
