Knicks’ J.R. Smith counts down to first full practice

J.R. Smith doesn’t have all his moves down pat yet, but he can’t wait to showcase what he has on Tuesday.

The Knicks will clear Smith to practice fully Tuesday in Toronto. The reigning NBA Sixth Man of the Year Award winner can start to erase the stench of his pot-smoking suspension, his wretched-shooting 2013 postseason and his decision to delay knee surgery until after his new contract was signed.

It will be a big day for Smith, who is expected to scrimmage. He is on target to play the Knicks’ final preseason game on Friday against Charlotte, according to coach Mike Woodson. The urgency to play the preseason finale is so Smith’s five-game suspension clock can start ticking with the season-opener on Oct. 30 and he can be back for the season’s sixth game against San Antonio.

“It’s hard trying to make a move you can normally make and you can’t make it,’’ said Smith, who has a good chance of being the Knicks’ starting shooting guard. “At times, it’s frustrating, but we’re confident I’ll be back better than ever soon.’’

On Sunday at Columbia’s Levien Gym, Smith participated in full-court 3-on-3 drills, but those featured no contact.

Tuesday will be the real deal, testing a left knee that underwent surgery to repair a chipped patellar tendon and a torn meniscus.

“Without a doubt [it will be exciting] to finally to get out there with my guys and get knocked around a little bit,’’ Smith said. “It gets frustrating looking on the court, see them practicing, working hard, the camaraderie. It gets frustrating.

“It will be great for me to be out there, not just for myself but the team.’’

Late in rehab, Smith still got reps in with his jump shot that vacated the premises during the Knicks’ second-round playoff series against Indiana. Asked if he thought his jumper will be rusty, Smith said: “I worked hard with our coaches so I can get my shot ready for this.

“It will be short the first few days from fatigue, running and bumping and grinding,” he said. “You got to have confidence in your shots. If you don’t have confidence in your shots, 90 percent of the time you’re not going to make it. I have ultimate confidence in my shot and shooting ability and so do the coaches. It’s not a worry at all.’’

The Knicks may not have their starting backcourt against the Raptors on Monday. Neither point guard Raymond Felton (hamstring strain) nor Iman Shumpert (elbow sprain) participated during Sunday’s 3-on-3 full-court session or scrimmage.

Felton won’t play and Shumpert is questionable.

Woodson marveled at the overflow crowd of 2,700 packed into Columbia’s gym.

“It’s the first time I’ve been to Columbia,’’ Woodson said. “It’s a beautiful here. True Knicks fans.”

Amar’e Stoudemire didn’t participate Sunday because it was his “slow day’’ after doing his first contract practice Saturday. He will make the trip and scrimmage Tuesday.
