Jeff Hornacek said new point guard Derrick Rose won’t return to the Knicks until his civil rape trial is over, and he’s trying to hold back on some teachings until that time.

Rose’s trial is not expected to end until next week after a federal judge ruled Wednesday against a mistrial due to Rose’s accuser withholding three potentially damaging texts.

At the earliest, jury deliberations are not expected until Monday, meaning Rose will miss his third straight preseason game Saturday, against the Celtics. Wednesday was the fourth practice Rose has missed, as the Knicks’ biggest offseason addition is trying to learn a brand-new, complicated hybrid offense.

“Whenever it’s over, he’ll be here,’’ Hornacek said. “I’m hoping that’s sooner than later. We’ll just catch him up on things. We’re trying to stall a little bit in putting some of the things in, so we don’t go over it again when he’s here. But we’re hoping it’s sooner than later.”

Rose left the Knicks for Los Angeles last week after Tuesday’s preseason opener in Houston. He’s accused of raping his former girlfriend with two other friends in 2013, with the accuser saying she was drugged beforehand and too drunk to consent.

“I’m not sure technically what he can do,’’ Hornacek added. “We said go ahead, take care of that. I don’t know, court rules. But he’s got to get that taken care of and he’ll be back.’’

Hornacek said he’s put off some of the defensive strategies along with additions to the triangle. The Knicks are incorporating a mix of Hornacek’s speedball attack from his Phoenix days with Phil Jackson’s triangle, which Rose already called “a little complicated.’’

Through text messages and one phone conversation, Hornacek has kept in touch with Rose.

“He’s a guy who has to, as a point guard, you’re the one who sees everything, where’s the best place to pass it,’’ Hornacek said. “That’s a familiarity.’’

Free-agent signee SG Courtney Lee has been quiet through three preseason games, taking 13 shots and logging just 16 points, prompting Hornacek to chat with him about being more assertive.

“We mentioned to him a few times – go ahead and shoot it,’’ Hornacek said. “He’s trying to make the right plays and feel his way. He’s a guy we expect to make those 3s. He’s a great shooter.”

Lee, who signed a four-year, $50 million deal, has gotten the message.

“I agree with him,’’ Lee said. “Preseason games, I’m being a little laid-back, feeling things out, trying to make the right plays, the right reads and keep the ball moving on offense. Talking with him and watching film, seeing where I can pick my spots, I definitely will go out there and be more aggressive [Saturday].’’
