Miami Heat star Jimmy Butler will miss the entire first-round playoff series against the Boston Celtics due to a sprained MCL in his right knee. Butler suffered the injury in the Heat’s Play-In Tournament loss to the Atlanta Hawks last Wednesday and has not played since. The absence of Butler is a major blow to the Heat, who have struggled without him. In Game 1 of the Celtics series, the Heat were defeated by 20 points, highlighting the team’s need for Butler’s leadership and production.
