Gaborik had two points in three games for the Rangers before he was injured on Oct. 15.
"It's feeling confident enough and comfortable enough to jump back into things, and after today I feel that way," said Gaborik, according to the Rangers website. "It's been awhile since I played and I am very anxious to get back in there."
He will wear extra padding under his shoulder pads during the Sabres game as a precaution.
Coach John Tortorella let Gaborik make the decision to play on his own.
"I've stayed away from him because I think the players feel more comfortable going to the trainers to talk about [injuries]," said Tortorella, according to the Rangers site. "I'm not a big guy about he's 100 percent or he's 95 percent. Can you play or not? And Gabi knows that, and he came to me after practice and said he's ready to play. And I said OK!"
Tortorella also revealed that defenseman Michal Rozsival will miss the next 7-10 days due to a bad shoulder that he has been struggling with for a while.
According to the Rangers website, Tortorella said, "He has been playing through a really bad shoulder for quite awhile and it just got to the point now where he just can't handle it and he's worried about hurting the club."
