Latvian rookie Kristaps Porzingis still hasn’t decided if he will play for the Knicks summer league, according to multiple sources. The 7-foot-3 Porzingis, coming off a rugged Spanish League season with Sevilla, had been nursing hip tightness entering the NBA draft — an injury that cut short his pre-draft workout with the Knicks.

Porzingis said before the draft the injury was “nothing serious,’’ but after he was selected No. 4 by the Knicks, his brother went on radio to say his summer-league status was an unknown. The Knicks said a day later they still expected him to play, but with the team debuting Saturday in Las Vegas, it is still being decided. The first official practice is Thursday in Vegas.

Latvia Basketball announced Monday Porzingis would not play for its national team this month in its Olympic qualifying event because he wanted to spend the summer working out with Knicks coaches.

“It was tough decision, but I believe that in the future it will benefit me and Latvia’s basketball,’’ Porzingis said.
