Porzingis (calf) won't be available for Monday's game against Indiana, Jay King of The Athletic reports.

Porzingis will miss his fourth consecutive game due to a left calf strain, with his upcoming absence coming in an In-Season Tournament Quarterfinal game. The big man expressed hope last week that he would be available to play at some point during the In-Season Tournament, so he could be an option to play Thursday, should the Celtics advance to the semifinal round. Al Horford will likely pick up another start at center Monday in place of Porzingis.
