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 “to help in any way.’’

Noah will miss the final contest of his 20-game suspension Saturday when the Knicks (6-5) host the Kings (3-8), then be back on the 15-man roster for a Monday home game against the Cavaliers.

“All I can do is just be as ready as possible,’’ said Noah, whose suspension for the performance-enhancing drug Androgen started with eight games remaining 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. It’s tough you know? We have a lot of very good players at our position.”

With Noah, the Knicks have four centers vying for playing time – unless they trade one of them by Monday. The Knicks have gauged backup Kyle O’Quinn’s trade value across the first 11 games and it’s increased because of his gritty 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.

“I’m here every day in practice, so I know what’s going on,’’ Noah said. “I’m definitely a work in progress. It’s been very humbling.’’

Coach Jeff Hornacek praised Noah, a former Defensive Player of The Year, during the preseason for looking a lot more spry than his first disastrous season with the Knicks, when he played 46 games. But he knows something has to shake up with the roster and indicated he’d like to roll with Noah eventually.

The Knicks have to create one spot on the roster for Noah, and beyond the centers, Ramon Sessions, Mindaugas Kuzminskas and Michael Beasley are not safe, either. The center glut, though, is so crowded Willy Hernangomez has been mostly out of the rotation.

“We’re going to have to figure that out when we can,’’ Hornacek said. “With Scott [Perry] trying to figure out what our moves are. If all four centers are there, it’s going to be a situation where we’re to have to take a look at whether we can keep all four of them out there. It’s already tough enough trying to get Willy minutes. But Jo, he’s been working hard in practice. He’s been doing a great job. So we’ll try to get him worked in at some point.”

Noah, who battled various injuries last season, eventually needing rotator-cuff surgery, has been allowed to practice, compete at morning shootarounds and has traveled with the club. He’s not allowed to be in the arena two hours before tip off. He sees a renewed tenacity in the Knicks’ surprisingly solid 6-5 start, gleaned from watching on TV.

“I think they’re playing hard,’’ said Noah, whose four-year, $72 million contract is virtually untradeable. “I think this is a team that the people in New York should be excited about. The future is definitely really bright. This is a team that’s gonna work hard every night. Definitely have a long way to go but it’s an exciting team to be around.”

He will never criticize ousted Phil Jackson, as he’s read all his books, but Noah admitted, “Yeah it’s definitely a different vibe but I’ll always love Phil.’’

The night of road games, he’s been in his hotel watching the game on television alone – the toughest part.

“I’m not gonna lie, it was very humbling, very tough, to not be able to be with the guys, to have to stay back and watch the games alone, even on the bus,’’ Noah said. “That’s been tough.”

Noah has attempted to bring leadership and has talked with Hernangomez for support. Noah said he had it tough early in his career with DNPs. But for now, Noah, a Hells Kitchen product, still thinks he can contribute on the court.

“Right now I still feel like I have a great opportunity to be able play at home,” Noah said. “That’s something that I’m not going to take for granted. And it was taken away from me because of a bad decision.

“Knicks fans are hungry fans and they appreciate hard work. Last year was a tough year and there was a lot of frustration with the way we conducted ourselves and the way I conducted myself with the suspension.”
