Celtics’ Porziņģis suffers displaced tendon, Game 3 status unclear

DALLAS — Boston Celtics star center Kristaps Porziņģis suffered a displaced tendon in his left leg, leaving his status day to day and his availability for Game 3 of the NBA Finals in question.

In announcing the injury, the Celtics said Porziņģis suffered a “torn medial retinaculum allowing dislocation of the posterior tibialis” of his left leg, which means a tear of connective tissue near the ankle, leading to a displaced tendon. Boston called the injury “rare” and said Porziņģis consulted numerous specialists.

According to the National Library of Medicine, the vast majority of cases like this are resolved surgically.

“It’s a serious injury,” Celtics coach Joe Mazzulla said before the Celtics practiced in Dallas. “He’s doing anything and everything he can to be ready for the game tomorrow. … At the end of the day, our team and the medical team are not going to put him in any bad situations — so we’ve taken the decision to play out of his hands.”

Porziņģis, who is averaging 12.5 points and 5.0 rebounds off the bench in the finals, said, “I’m going to do everything I can to be out there tomorrow. I am (optimistic), of course, I have to be.”

The new injury is not related to the calf injury that kept Porziņģis out for 10 games earlier in the playoffs, the team said. Patients who do not have immediate access to the level of care the Celtics do typically go undiagnosed for an extended period when dealing with the injury Porziņģis has, the National Library of Medicine states. Those patients may think they have an ankle sprain or, according to the NLM, a benign muscle tumor around the ankle.

The Celtics lead the series 2-0 with Game 3 at 8:30 p.m. (ET) Wednesday at Dallas’ American Airlines Center.

Dallas star Luka Dončić, who is averaging 31 points per game in the Mavs’ two losses, declared that his sore chest was better on Tuesday. He played Sunday’s 105-98 Game 2 loss with a chest bruise painful enough that he was questionable to play.

A league source said Dončić received a pain-killing injection before Game 2 and may need another before Game 3.

“I feel good,” Dončić said Tuesday. “I don’t want to get into any more details, but I feel good.”

Dončić also said the Mavericks’ main problem in the series was “we can’t really score.”

The Mavs are shooting 44.5 percent, but their 3-point shooting (24.5 percent) and, even worse, foul shooting (65.1 percent) have not been at a championship level.

The Celtics have the top-rated defense in the playoffs (107.6 points allowed per 100 possessions — mostly without Porziņģis on the court) and were the second-best defense during the regular season.

“I think we’re getting some great looks,” Dončić said. “We have confidence everybody can make a shot … on our team. We just got to keep believing in it.”
