The Knicks had to wait until they were out of the country to finally get some of their injured players back on the practice court together for a scrimmage for the first time in training camp.

J.R. Smith Amar’e Stoudemire and Kenyon Martin all received high marks from coach Mike Woodson after the banged-up trio participated in the team’s 5-on-5 scrimmage Tuesday at Humber College.

“Pretty intense scrimmage and it was good to see Amar’e Kenyon and J.R. out on the floor” Woodson said. “That’s a lot of talent in terms of depth. . . . It was kind of nice to have them. We’ll gauge it after today and see how these guys feel (Wednesday).”

After the Knicks face Milwaukee in Green Bay on Wednesday Woodson said only Smith is “a possibility” among that trio to play in Friday’s preseason finale against Charlotte at the Garden. While Smith’s five-game regular-season suspension for violating the NBA’s drug policy will kick in as soon as he is deemed healthy Stoudemire and Martin both are targeting to be available for opening night next Wednesday against Milwaukee. “That’s my goal. I didn’t play the opener last year. So I want to get out there and see what I can do. But again if I keep improving my body keeps getting stronger we’ll see how it goes” said Stoudemire who underwent a third knee surgery in the past two years over the summer. “(The scrimmage) went great. I felt extremely strong. My legs are as strong as they’ve ever been before. I felt no discomfort at all I felt no pain at all. So a great great sign.”

Woodson appeared even more enthused about Smith’s play in his first 5-on-5 contact since undergoing left-knee surgery in July.

“The way J.R. moved today I thought it’s like he hasn’t missed a beat” Woodson said. “But again he only played a 10-minute spurt. J.R.’s a guy we’ll be asking to play 30 minutes a night. We just have to make sure he’s right.”

Said Smith: “I was able to do everything and that was the best part things I’m used to doing. I was able to step back with no problem with no pain and to feel comfortable as normal as possible is the best part of it. When I jump off it feels normal. It’s still losing a little strength in there as far as athletic ability not jumping as high as I was at one point but that will come once I get my legs fully under me.”

Unlike Stoudemire and Martin who has been hampered throughout camp by an ankle injury suffered late last season Smith expects to return without any restrictions on how much he can play once his suspension is served.

“No no minute restriction” Smith said. “That’s the one thing I was thinking about the most coming in (after) having the surgery is coming back and being on a minute restriction. When I come back I want to be able to go out there full strength and full head of steam with no restrictions no nothing. If I’m on a restriction that means I’m not at the best ability to help the team.”
