When the Nets start training camp on Tuesday, they actually will have oft-injured Ben Simmons cleared and ready to go.

But they won’t have veteran Bojan Bogdanovic, still recovering from surgery.

Simmons, the only All-Star on the Nets roster, had been cleared for 5-on-5 and full contact for some time ago as The Post reported back on Sept. 7.

But getting him back on the court after three years of back woes will be key for the Nets, who finally look to get if not a prime Simmons at least a quasi-healthy one.

“Yeah, I certainly hope so for Ben’s sake,” general manager Sean Marks said on Thursday. “You never want to see anybody have to go through a couple of back surgeries like [he] had and sit out. Being the competitive guy he is, you wish him well, and you hope he can get out there on the court.

“From what we’ve seen so far with Ben, Ben will be a full go in camp, which for us, that’s exciting to see. And for him, he’s champing at the bit to be able to get out there and contribute. So this is a big year for him, just like it is for the rest of us.”

Simmons’ nerve impingement issues came back last season, and he had season-ending microscopic partial discectomy in March.

It was his second such procedure in the past two years, and he’s missed 189 of 246 games over the prior three seasons, including all eight of Brooklyn’s playoff tilts in consecutive first-round exits.

“Ben’s been very good. Had a successful surgery, really good summer,” first-year head coach Jordi Fernandez said. “He sits in a very good place, and like Sean just said, he’ll be full go to start camp.”

It’s become an annual refrain regarding Simmons.

But the three-time All-Star has essentially become an invisible man.

Simmon has missed a staggering 189 of 246 games over the prior three seasons, including all eight of the Nets playoff tilts.

So for Fernandez — who spent time in Miami with Simmons this summer as he rehabbed — the point guard’s availability is far more important than his fit or his floor spacing.

The Nets were 7-8 last season with Simmons, but 25-42 without him.

“If you think about it, a healthy Ben Simmons … the number one thing for him and the thing we care the most about is his health. Ben being healthy, Ben is a very good player,” Fernandez said. “And Ben being healthy, he can rebound, push, do all that stuff that can help us create really good shots.

“But we’ll treat him the same way as everybody else. We’ll go through practices, we evaluate how everybody feels, and then we’ll make decisions. And that’s why we have a great medical staff, performance staff, and we’ll work all together as a unit. So excited to see Ben on the court from Day 1.”

The Nets won’t have Bogdanovic from Day 1.

The sweet-shooting small forward arrived from the Knicks in the Mikal Bridges trade, but he’s still recovering from season-ending surgeries on his left foot and wrist.

“So starting with Bojan, successful surgery. He’s working. He’s in a very good place. We see him every day putting in his work. He’s not going to be ready to start camp,” Fernandez said. “That’s what we’re gonna do at this moment.”

Other than leading scorer Cam Thomas, Bogdanovic is the only player on the Nets roster who has ever averaged 20 points — in 2019-20 and again in 2022-23, even averaging 20.2 last season for woebegone Detroit before being dealt to the Knicks at the trade deadline.

But after suffering the leg injury on April 24 — and having surgery six days later — the Knicks said he’d be reevaluated in three months.

Bogdanovic has an expiring $19 million contract that became fully guaranteed on June 28.

To date, the forward is not believed to have had any conversations with the Nets on a buyout, focused solely on getting back on the floor.
