CLEVELAND -- Cavaliers star guard Donovan Mitchell is questionable for Game 4 of Cleveland's Eastern Conference semifinal against the Boston Celtics on Monday night due to a left calf strain.

Mitchell had 33 points in 43 minutes in Game 3 but appeared to be limping in the fourth quarter of Cleveland's 106-93 loss to Boston on Saturday night.

The Celtics lead the series 2-1.

Mitchell has averaged 29.6 points, 5.4 rebounds and 4.7 assists across 10 postseason games for Cleveland, including scoring at least 25 points in six straight -- something only LeBron James had done in Cavaliers history.

In addition to Mitchell, Cavaliers starting center Jarrett Allen remains questionable because of a bruised rib, an injury that has kept him out for the past six playoff contests, dating back to Game 5 of the Cavaliers' first-round series against the Orlando Magic.
