Luol Deng added 17 points and 11 rebounds for the Bulls, hitting two free throws with 8.8 seconds left to seal the win. Chicago led most of the way in winning for the fifth time in seven games.
Paul Millsap and Jeff Teague scored 16 points apiece for the Hawks.
A 3-pointer by Kyle Korver that would have cut the Bulls’ lead to 84-82 with 4:16 left was overturned and ruled a shot clock violation upon review.
Korver extended his NBA record of games with at least one 3-pointer made to 103 straight when he hit the first of his two 3-pointers with 9:59 left in the first quarter. Korver finished with eight points.
The Hawks tied the game 67-all with 11:12 left on Mike Scott’s free throw. It was the first time the Bulls hadn’t led since 6:19 in the first quarter. But Dunleavy answered with a 3-pointer, Joakim Noah scored on a putback and Jimmy Butler made a layup to put the Bulls ahead 74-69 with 8:41 left.
Atlanta pulled to within one on Teague’s layup with 5:38 left, but Dunleavy responded with a jumper and Taj Gibson scored on a dunk for an 84-79 lead.
