Backup guard Tony Allen, however, was sick and missed the game.
Garnett's return didn't help the Celtics. He played 28 minutes, scored 14 points and pulled down nine rebounds, but Boston lost to Chicago 101-93. The Celts' sixth loss in nine games assured them of the fourth spot in the Eastern Conference behind Atlanta.
Coach Doc Rivers said before the game that he planned to monitor Garnett's minutes after resting him against Milwaukee on Saturday night. He also considered giving Paul Pierce the night off, but "he wanted to play."
Pierce led the team with 28 points.
