Terry had been recovering from offseason surgery on his left knee. He went through his first full practice Friday.
"It's gonna be great, getting back out there with my teammates," Terry said Sunday. "I've been out there in practice the last couple days. Everything's been going fine, no setbacks. So just being able to get out there in real live game action, it's gonna be good."
Terry said his plan all along was to play in the team's final two preseason games. The Nets wrap up the preseason in Miami Friday night. Terry added that his knee feels strong.
Nets point guard Deron Williams, riding a stationary bike prior to Sunday's open practice at the Barclays Center, expressed his frustration over not being fully healthy.
Williams is still recovering from a sprained right ankle injury he suffered during an offseason workout in Utah. He has been limited in practice and has yet to play in a preseason game.
There is no definitive timetable for his return.
"It's frustrating having to sit out, frustrating having to watch them play games in the preseason. Really, practice, practice has been fun to watch; but also frustrating to watch because I can't be out there," Williams said.
"It's gonna be fun," Terry said of making his return to Boston. "For me, I was only there a year. The fans were great, the city was good to me. There's no hard feelings or ill-emotions. I'm gonna see some of my friends; Avery Bradley s almost like a brother to me. Seeing him will be good."
Terry does not know how many minutes he will play Wednesday night.
"He looks great," Nets coach Jason Kidd said. "When he's with the white team (in practice) it makes him that much more dangerous in a sense he gets the ball in the basket and understands how to play, sets screens, does all the little things. He's a competitive. He hates to lose so that's what he brings to the table and that's what he's been doing the last couple days.
"No matter who it's against, just want him to get some time on the floor and see him with some different guys, coming off the bench we'll see how he looks but just to give him as many minutes without stretching him too long."
Terry, 36, is a career 37.9 percent shooter from 3-point range and won the NBA's Sixth Man of the Year award in 2009.
"His winning attitude, being a professional, understanding what it takes to be successful, coming off the bench. He won a sixth man of the year and won a championship," Kidd said. "Understanding that coming off the bench is just as important as being a starter because the guys coming off the bench have to pick up the starters, if they're up or down, so it's a difficult job but he's the perfect example of teaching guys coming off the bench how to be ready."
