Joakim Noah has gone from being banished by the NBA for taking a banned supplement to being banished by his own team.

For the second straight game since returning from his 20-game drug suspension dating to last season, the $72 million man was inactive Wednesday and Knicks coach Jeff Hornacek doesn’t foresee an immediate change.

Noah, after a hard workout on the court with assistant coach David Bliss, declined comment.

“We want him to be involved,’’ Hornacek said. “[He wants] to be involved. We don’t know when the time will come when he’s active.”

The issue is the Knicks already have a center glut with Enes Kanter as the starter, Kyle O’Quinn as the primary backup and Willy Hernangomez, a building block, fighting for minutes. Hornacek said he’s not sure he will dress four centers anytime soon.

“I don’t know,’’ Hornacek said. “It’s possible, depending on what other positions look like. We have guys at multiple positions. I’m not looking to do that right away.’’

The Knicks will need to at least showcase Noah if they have any chance of dealing him to a title contender gambling for defensive help off the bench.

Perhaps their only hope is Minnesota president/coach Tom Thibodeau, who guided Noah when he was first-team All-NBA for the Bulls in 2014.

The Knicks are in no rush to use the stretch provision and waive Noah, which probably is where this eventually ends up.

Using the stretch provision now or using it after the season would have the same consequences and cap savings. So the Knicks will bide their time and see if Noah drinks from the fountain of youth.

If the Knicks used the stretch provision anytime between now and Sept. 1, before the start of next year’s training camp, his remaining two years of $37.8 million would be stretched across five years.

If they stretch him now or after the season, it would give the Knicks $11 million of extra cap room for next summer and $12 million of extra cap room for the following summer.

Noah’s cap figure would be fixed at $7.5 million from 2108 through 2022. If the Knicks flat-out waived him without the stretch — or bought him out — they likely get no cap savings for 2018 and 2019, but would be clear of his salary in the summer of 2020. It’s a trade-off.

The Knicks’ philosophy is that Noah’s serving as a mentor for Kanter, 25, and more importantly, Hernangomez, 23. But ex-president Phil Jackson is gone and there’s no allegiance to the Noah signing.

On Monday, Hornacek named Noah the defensive captain upon his return from suspension and he sits behind the bench to better communicate. The Knicks coach feels badly because Noah has looked very good in practice.

“We talked about it,’’ Hornacek said of the situation. “With the amount of centers, we can’t find minutes for Willy. We have to play it by ear. The NBA should not have an inactive list. If you have 15 guys on roster, you should have 15 guys on the bench.

“It’s a tough spot. He’s a great team guy. He sees how we’re playing. He’s still part of the team if inactive or not. He doesn’t want to rock the boat but he is competitive and wants to be out there to help us.”

Noah already has talked about being a guide for Hernangomez during this current playing-time crisis when the second-year player has been mostly out of the rotation.

He wanted this season to be one of redemption. Playing 46 games in his first season in New York, he was hobbled by a recurring hamstring injury. After his suspension for taking Androgen to help his healing, it was deemed he also needed shoulder surgery. It was the worst possible season a player can have after signing a $72 million pact — the Hell’s Kitchen homecoming all gone wrong.

Noah is the Bulls’ all-time leader in offensive rebounds (1,910), but Kanter has taken that up as his specialty. All Noah can do is wait.
