Cavs star Donovan Mitchell (calf) out for Game 4

Cleveland Cavaliers star guard Donovan Mitchell has a left calf strain and will miss Game 4 of the team's second-round playoff series against the Boston Celtics on Monday night.

Mitchell was listed as questionable on the team's injury report earlier Monday, and he did not participate in the open portion of the Cavs' morning shootaround, instead undergoing treatment on the calf.

The team ruled Mitchell out less than an hour before tipoff.

The Cavaliers trail top-seeded Boston 2-1 in the series and will try to even the series without their leading scorer. Mitchell was averaging 29.6 points per game over Cleveland's first 10 playoff games after posting a 26.6 ppg average in the regular season.

Mitchell is also averaging 5.4 rebounds and 4.7 assists per game this postseason.

Cleveland big man Jarrett Allen (ribs) will miss his seventh straight game.
