The Boston Celtics have struggled to get a strong showing from Kristaps Porzingis, who is still dealing with a linger illness from the winter.

The 7-3 Porzingis logged only 27 combined minutes in the Knicks’ two victories earlier this week in Boston due to what he believes “probably” are the aftereffects of an upper-respiratory viral illness that sidelined him for nine games in February and March.

Celtics center Kristaps Porzingis came off the bench for the second straight game after an ominous report about his lingering illness.

Celtics coach Joe Mazzulla said Kristaps Porzingis has been dealing with an on and off illness since he returned to action in March.

As the Knicks made yet another soul-crushing run in the fourth quarter Wednesday, all Kristaps Porzingis could do was watch.

When Kristaps Porzingis concluded his first six-minute shift Wednesday night, he looked like he’d just run a marathon. His breathing was heavy. He was visibly fatigued. When he took his seat on the Celtics bench, he dropped his head and stared at the TD Garden parquet.

Porzingis said that the virus caused his energy to crash right before Game 1. The post How Kristaps Porzingis is reportedly treating virus that’s re-emerged during Celtics-Knicks series appeared first on Boston.
