INDIANAPOLIS — Karl-Anthony Towns was down on the court, writhing in pain and clutching his left knee, with barely two minutes remaining Tuesday night.

Towns limped back onto the floor and finished out the Knicks’ 130-121 loss to the Pacers in Game 4, putting them in a 3-1 hole and on the brink of elimination.

The All-Star big man, who finished with 24 points and 12 rebounds in 37 minutes, also appeared to be favoring the same knee earlier in the game.

“I’m only thinking about this loss, I’m not thinking about that right now,” Towns replied when asked afterward if there was any concern on his part about playing in Game 5 Thursday night back in New York. “It’s disappointing when you don’t get a win. Just didn’t do enough to get the job done tonight.”

Knicks coach Tom Thibodeau said he believed “it’s a good sign” that Towns was able to remain in the game, and “we’ll see where he is after he gets evaluated” by the medical staff.

Towns collided with Indiana’s Aaron Nesmith with the Knicks trailing by seven with 2:11 remaining.

He initially was whistled for an offensive foul, but Thibodeau challenged the call and it was ruled that Towns had been pushed into Nesmith by Pacers center Myles Turner.

Towns, who had scored 20 points in the fourth quarter of the Knicks comeback win two nights earlier in Game 3, only played four minutes with four points in the first quarter after picking up two personal fouls.

Starting at power forward for the second consecutive game with Mitchell Robinson replacing Josh Hart in the starting lineup, Towns netted 10 points in the second quarter to reach 14 by halftime.

Still, he attempted only two 3-pointers in the game, making one, after shooting 9-for-20 from long range in the first three games of the series.
