Tempers are flaring between the Chicago Bulls and Boston Celtics.
Marcus Smart didn't seem to appreciate Jimmy Butler's physicality Sunday, as the All-Star was glued to him and helped force a turnover in the second quarter of Game 4.
After Isaiah Canaan poked the ball away and scored, Smart picked it up, then engaged in a shoving match and apparent war of words with Butler.
Officials and teammates separated them, and they were assessed a double technical foul.
