The Celtics were up 103-102 when the foul was called, but the Bulls won 104-103 after Butler made both of his free throws.
Smart saidhe was punished for playing good defense, while Butler held firm in his belief that he was fouled by Smart.
After taking a look at the play, what are your thoughts on the call?
Butler will represent the Bulls in this weekend's All-Star Game. Smart was not selected as an All-Star; however, teammate Isaiah Thomas will be on the bench for the Eastern Conference, set to be coached by the Celtics' Brad Stevens.
