Parise was in the lineup Saturday night as the Devils took on the Canadiens.
The Devils officially activated Parise from injured reserve Saturday afternoon.
Parise hadn't played since Oct. 30 in Los Angeles. He underwent arthroscopic surgery to repair a torn meniscus in his right knee Nov. 2.
Coach Jacques Lemaire said it was Parise's decision as to whether he felt ready to play.
"It is up to me," Parise said, according to the Newark Star-Ledger. "I said yes. I'm looking forward to it."
Goaltender Martin Brodeur understood the excitement that Parise felt Saturday. Brodeur came back from a serious injury during the 2008-09 season, when he missed 50 games with a torn left biceps muscle.
"You have to feel for him for what he's been through with his rehab. I went through it a few years back and I know how hard it is to be by yourself for a long period of time and not see the light at the end of the tunnel," Brodeur said, according to the paper. "Finally tonight it's going to be a night for him to be able to get on the ice and play and be part of the team, to have that team atmosphere."
