CLEVELAND — Just when the Knicks got back to full strength for the first time in weeks, they suddenly have a new injury concern ahead of Game 2 against the Cavaliers.

Game 1 hero Josh Hart’s status for Tuesday’s game is in question after he was limited in practice Monday due to a sprained left ankle, according to Knicks coach Tom Thibodeau.

“We’ll see how he feels tomorrow,” Thibodeau said. Usually with sprains like that, it’s more how you feel the next day. He said he felt fine in the game, so we’ll see where he is tomorrow.”

The Knicks’ key trade-deadline acquisition appeared to land on teammate Julius Randle’s foot following a tip-in by Cleveland center Jarrett Allen late in the fourth quarter, one possession actually before Hart nailed the go-ahead 3-pointer with 1:49 to play in the Knicks’ 101-97 victory.

Randle and Jalen Brunson had returned to the Knicks’ lineup for Game 1.

Randle sat out the final five games of the regular season with a sprained ankle, while Brunson played in only four of the final 14 games due to foot and hand injuries.

The 28-year-old Hart has not missed a game since joining the lineup following a Feb. 8 trade from Portland.

He has emerged as a versatile and valuable role player off the bench, with the Knicks going 18-8 in his 26 appearances, including Saturday’s victory in the series opener.

“He [practiced] some. It was pretty light. Just got mainly treatment,” Thibodeau said. “He did a little bit of what we were doing. But more mental today, just get treatment, and again tomorrow, see where he is.”
