Joakim Noah doesn’t know how much or if he’ll play with the club’s center glut, but he’s delighted his drug suspension is about to end.

Noah will miss his 12th and final game Saturday when the Knicks host the Kings, then be back on the 15-man roster for a Monday home game against the Cavaliers.

The Knicks will then have four centers vying for playing time – unless they trade one of them by Sunday night. The Knicks have gauged backup Kyle O’Quinn’s trade value across the first 11 games and it’s increased because of his solid play as Enes Kanter’s backup. After the Bucks traded center Greg Monroe for Eric Bledsoe, it’s been reported they are looking for another reserve center.

“All I can do is just be as ready as possible,’’ said Noah, whose suspension for the performance-enhancing drug Androgen started last season when he was injured. “I feel like I’ve put myself in that position, grinding hard. Whatever my role is I’ll accept it.

“I’m here every day in practice, so I know what’s going on. Obviously, I’m definitely a work in progress. But I’m working every day and when my number’s called, I’ll be ready.”

Coach Jeff Hornacek praised Noah during preseason for looking a lot more spry than his first disastrous season with the Knicks. But he knows something has to shake up with the roster and indicated he’d like to roll with Noah eventually.
