Kemba Walker got his knee drained and received a Synvisc injection to help manage the swelling and soreness.
Brad Stevens said that the knee injury was unlikely to be a long-term issue.
"Knee looks good structurally. But he's going to be managing it and dealing with it, as he has all year," said Stevens.
Walker, who played 29 minutes in the All-Star Game, was ruled out for Friday's game against the Timberwolves.
