In Boston’s first game without Jayson Tatum (Achilles), Porzingis will make a return to the starting unit in a bigger lineup for the Celtics. Payton Pritchard, Sam Hauser and Luke Kornet should fill out the reserve minutes.

Porzingis’ stamina has been an issue this series, with the Celtics’ center coming off the bench and only playing 14 minutes in Wednesday’s Game 2 defeat. Whether he starts or comes off the bench for Game 3 has not been determined. Al Horford would remain in the starting lineup if Celtics coach Joe Mazzulla decides to use Porzingis in a reserve role.

After an illness limited him to 13 first-half minutes in Boston’s series-opening defeat on Monday, Porzingis came off the bench in Game 2. Unfortunately, he could only give the Celtics 14 minutes. Following the game, Porzingis said his current problem may be related to the upper respiratory ailment that sidelined him for eight games late in the regular season. “Probably, probably,” Porzingis said. “I’ve had like ups and downs throughout until this point. Just now, had a big crash. Now, my energy, my everything, hasn’t been good, but who cares? Have to move forward and it will get better from this point.” While Boston’s shot selection was the focus following its two home defeats, Porzingis’ limited availability has also been a factor. He’ll hope to return to full health in time for Game 3 on Saturday afternoon. Al Horford may continue to start, with Luke Kornet playing a significant role off the bench if Porzingis is still dealing with the lingering effects of the illness.

After exiting early from Game 1, Porzingis was made available for Game 2, but he only played a small role off the bench. Al Horford logged 29 minutes as a starter, while Luke Kornet played 18 minutes off the bench. Both bigs played more than Porzingis, who was only on the floor for 14 minutes. He’ll have a few days off before Game 3 on Saturday, which will hopefully be enough time for him to get back to full strength.
