Report: Porzingis out 2 weeks, will undergo evaluations for illness

Atlanta Hawks center Kristaps Porzingis will miss the next two weeks and undergo further evaluations while dealing with an illness, sources told ESPN's Shams Charania.

Last season, Porzingis, then with the Boston Celtics, battled an illness that he said kept sapping his energy. At the time, the one-time All-Star said doctors couldn't identify the ailment, which also limited him during the postseason.

In October, Porzingis revealed that he had been diagnosed with postural orthostatic tachycardia syndrome (POTS), a disorder of the nervous system that causes an increased heart rate and lightheadedness, among other symptoms, when a person stands.

"It hit me, and it hit me like a truck," the Hawks big man told The Athletic's Fred Katz then. "The breathing wasn't good. I did everything I could potentially to feel as good as I could, but my engine wasn't running the way I wanted."

Porzingis, who's played just once in the Hawks' last seven games, is averaging 19.2 points, 5.6 rebounds, and 3.1 assists in 13 contests this season.

He played a season-low 20:29 during his last appearance on Dec. 5, a 134-133 loss to the Denver Nuggets in which he came off the bench for the first time this season. The 30-year-old was returning from a four-game absence but said he didn't believe it was due to the same issue that plagued him in Boston.

"I just wasn't feeling too good, honestly," Porzingis said postgame, according to team reporter Kevin Chouinard. "Just not being healthy healthy, you know? But I wouldn't say it's the same stuff from last season, so that's good.

"I think I kind of put that behind me even this summer playing for the national team, but anyway, just catching whatever, it's frustrating, you know? I want to be healthy. And I will be healthy."

Porzingis is in the final season of a two-year, $60-million extension he signed with the Celtics. He'll become an unrestricted free agent this summer.
