DALLAS — Kristaps Porzingis did not play for the Boston Celtics in Game 3 of the NBA Finals on Wednesday night because of a rare tendon injury in his lower left leg suffered in the previous game.
The Celtics announced about two hours before tipoff that Porzingis was out for that game against the Dallas Mavericks, but coach Joe Mazzulla later left open the possibility of the center being ready for Game 4.
''The medical team and the staff decided it wasn't what was best for him," Mazzulla said about Game 3. "It'll just be a day-to-day thing, see how he is tomorrow and the next day. ... He didn't look right. That was it. I was not involved in it. It was out of his hands.''
The 28-year-old Porzingis had missed 10 consecutive playoff games because of a right calf strain before returning last week for the start of the NBA Finals, and helped the Celtics take a 2-0 series lead against his former team. He jump-started the Celtics with 11 points and two blocks in the first quarter of their Game 1 win, then had 12 points in the game in which he got hurt.
Porzingis has said he felt something after bumping knees Sunday night with Dallas center Dereck Lively II but kept playing. He left the game in the final minute of the third quarter and played only about 3 1/2 minutes in the fourth.
The 7-foot-2 Latvian has a tear in the tissue that holds tendons in place. The Celtics said it was unrelated to the calf strain he sustained in Game 4 of the first round against Miami on April 29.
Al Horford, who turned 38 last week, started at center against the Mavs, like he has since Game 5 against the Heat. He scored the first five points for the Celtics, on a short jumper and a 3-pointer.
After the team announced the injury Tuesday, Porzingis said he was going through constant treatment and doing everything the medical staff told him. He said he would do whatever he could to play, but acknowledged that he ''can't trick them into allowing me to play."
