Butler proves a pain to Celtics

All-Star's clutch shooting lifts Bulls to unlikely win over Boston

Jimmy Butler drained two free throws with less than a second left on the clock to lift the Chicago Bulls to a 104-103 victory over the Boston Celtics on Thursday night.

Butler's clutch foul shots with 0.9 remaining capped a memorable duel with fellow All-Star Isaiah Thomas in the NBA's final game before the break.
