Knicks veteran center DeAndre Jordan introduced rookie Mitchell Robinson to his old Clippers mentor Marcus Camby late Thursday in the locker room.

It was the lone positive to come out of Thursday night’s late-game collapse against the Cavaliers.

Camby, the ex-Knick shot-blocking center who starred on their 1999 Finals team and returned as a locker-room leader on the 54-win club of 2012-13, made a rare Garden appearance.

Summoned by David Fizdale, Camby is another prominent Knicks alum the first-year coach wanted to speak to Robinson, who is fast emerging as the franchise’s No. 1 prospect.

Call it a Camby-Jordan-Robinson tutoring triangle — one that came full circle, if you will.

Camby took Jordan under his wing when Jordan debuted with the Clippers. Since arriving in New York last month, Jordan, 30, has taken over as Robinson’s unofficial big-man whisperer. And now Camby gets to help Jordan help the 7-foot-1 Robinson.

Camby recalled Jordan used to fetch him his donuts.

“It’s kind of crazy — when I was with DeAndre and the Clippers, he was my rookie [in 2008-09],” Camby said on MSG Network. “He was my Krispy Kreme go-to guy, my guy who would drive me to practice. I’ve watched him mature each year, but I was in his ear constantly on what he could do better. We watched a lot of film together. He listens, was a great pupil of mine. I’m happy he’s done great things in the NBA.”

Now Jordan and Camby, who averaged 2.4 blocks in his career, will get to help Robinson, showing potential to be the league’s best shot-blocker. Fizdale credits Jordan’s arrival as a trigger to Robinson’s surge. Since Feb. 5, Robinson is averaging 11.3 points 8.8 rebounds, 3.4 blocks while shooting 71.4 percent.

The irony is delicious. Who knows if Jordan would have embraced this new mentoring role on a tank machine if it wasn’t for Camby’s influence a long while ago?

Friday was the final day Jordan could be waived and still be eligible for playoffs with another team. Jordan told The Post he is happy to stick past March 1 – unlike Wesley Matthews, bought out soon after the Kristaps Porzingis trade.

“(Marcus) was great for me,” Jordan told The Post. “I was 19 coming in. I didn’t know much about studying the game, studying players and their tendencies. He was one of the guys who really took me under his wing. He’s a big part of my communication on the floor today and how I study different players and what moves they like to do. He was the person I learned from.”

On Thursday, Camby scouted Robinson as he sat next to his old buddy Latrell Sprewell on celebrity row. Robinson notched 12 points with seven rebounds and two blocks and making all five shots from the field (all dunks).

“I think he has a tremendous upside,” Camby, who didn’t always have a good relationship with owner James Dolan, said as part of the MSG interview. “(I’ve been) talking to coach Fiz a lot through text messages and he’s trying to connect us to see if I can talk to him. He sees a lot of similarities in our game. Anything I can do for the youth to help them grow up, I’m all for it. I’m happy he’s with us.”

And Knicks brass is elated Jordan, an impending free agent, wanted to remain — with a chance of being part of the future. Don’t forget Jordan is extremely tight with Kevin Durant.

“(GM) Scott Perry and (president) Steve (Mills) had a lot to do with that as well,” Fizdale said. “(DeAndre) sees a situation as a good situation for this year, having a real purpose, and possibly in the future. He’s like having another coach on the bench.”

Asked why he decided to stick, Jordan said, “You want me to leave? Why do you keep asking me that? It’s what the league is about. It’s a fraternity. You learn from older guys like I learned from Marcus. Anytime you can help a younger player out that’s what you’re supposed to do. He’s playing well. We’ve played against each other in practice a lot. Its tough battles. He’s talking more. It’s something we all love to see.

“I’m happy. If I wasn’t happy I would’ve tried to get out of here. The fans here are great. I love what Fiz is doing.”

Jordan, who missed the past three games with a sprained ankle, said he’s a long shot to play Sunday in his return to Los Angeles against the Clippers, with whom he spent 10 seasons before signing with the Mavericks last summer.

The good news is Jordan already made his Staples Center homecoming in December with Dallas, securing 22 rebounds.

“I’m working every day to get it back right,” Jordan said. “We’re making a lot of progress. It will be soon.”
