Luol Deng scored 25 points and the Bulls won their third straight game with a 96-83 victory over the Boston Celtics on Thursday night.
The Celtics, whose only lead was 2-0, trailed 86-80 after Paul Pierce hit a 3-pointer with 3:50 left. But the Bulls scored eight of the next nine, six by Joakim Noah, to build the lead to 94-81.
Noah added 15 points and 11 rebounds for the Bulls, who led from 4-2 onward.
