The Celtics announced Tuesday that Porzingis suffered a torn medial retinaculum allowing dislocation of the posterior tibialis tendon in his left leg at 3:27 of the third quarter of Game 2. The injury is not related to Porzingis’ prior right calf injury that kept him out of the team’s lineup for most of the playoffs.

After consultation with numerous specialists regarding this rare injury, Porzingis’ availability for upcoming games will be determined day-to-day. He’s listed as questionable for Game 3 on the Celtics’ official injury report.
