Marcus Morris is cool with the NBA for deciding against taking any action on him for Monday’s Wizards’ incident but not so cool with Kevin Durant.

In responding to Durant’s comment that the Knicks are no longer “a cool’’ place to play, Morris added to his anti-KD tweet from Thursday.

“It’s me personally,’’ Morris said before the Knicks’ 115-99 preseason loss to the Wizards at the Garden. “Obviously reading what KD said about the cool thing, I never was a real fan of that. Being cool being in the NBA, me personally, I feel it’s a blessing.

“I get what he’s saying. Actually I have a good relationship with KD, but the cool part of playing in all cities? Is it cool to be playing in Utah. Is it cool to play in other places? It was just never a fan of the cool thing, making a decision on what’s cool.”

Morris, the Knicks new starting small forward who scored 21 points on Friday, was in jeopardy of missing the season opener after he got ejected in the first preseason game Monday in Washington, banging the ball off Justin Anderson’s head 13 seconds into the second half.

Before the rematch Friday at the Garden, Anderson said, “I’m not talking about that stuff.’’

Morris, the Post reported, will not get suspended. He expects, though to talk to the league.

“Hell yeah,’’ Morris when asked if he was relieved. “Guys like me, you never know. I’m grateful to be able to play in the regular season opener).” Morris added jokingly, “It’s cool I guess.’’

He was told the NBA may talk to him. “Not yet,’’ Morris said. “I’m pretty sure they will. We [the NBA] got some other stuff we’re dealing with. I’m a small fry compared to that.’’

The reference was the NBA’s roiling controversy in China.

“It’s over with man,’’ Morris said of the play in which he nearly clipped Anderson’s head with his elbow. “Time to move forward. I’m happy I’m not getting suspended. I’m happy I’m back with the team and playing the first game at the Garden.”

Kevin Knox missed the game with a strained calf.

“I don’t think it’s going to be something that keeps him out for a long time,’’ coach David Fizdale said. “From everything I’m hearing from our trainers, it’s just more being cautious right now than it is severe.”

Knox’s absence allowed rookie small forward Ignas Brazdeikis to make his debut, and he played seven minutes but did not score.

Brazdeikas did not play in the opener — partly because RJ Barrett played 39:20.

“Absolutely, especially with Kevin Knox out tonight, that opens up an opportunity for some of the young guys to get in there,’’ Fizdale said when asked about their second-round pick.
