Lazar, 22, had been a healthy scratch for the past four games but is slated to return to the lineup at the New Jersey Devils on Thursday (7 p.m. ET; MSG+, TSN5, RDS, NHL.TV).
"We're focused on playing the game and getting points," Senators center Derick Brassard said, "but I know our GM wants to win and [coach Guy Boucher] wants to win so if they can add a player that makes sense and it won't hurt the future of our team, I think he's going to do it. A couple days ago, [Dorion] kicked the tires on [Colorado Avalanche forward Matt] Duchene but didn't want to expose any players in our future.
"He's working really hard to help us make a big push for the playoffs, but as players we just have to focus on what we have to do now. We just have to play and control what we can."
Lazar, selected by the Senators with the No. 17 pick in the 2013 NHL Draft, had been a healthy scratch for five of the past seven games. The Senators are in second place in the Atlantic Division, six points behind the Montreal Canadiens, who have played four more games.
Lazar is in the final year of a three-year, entry-level contract he signed with the Senators on Sept. 17, 2013.
"Mental strength and toughness is definitely a big part of what I've had to focus on this season," Lazar said. "I can truthfully say when I first got called up this season and wasn't getting much of a look, it did affect me and I became a little bitter and sour but that didn't help me.
"You look at the bye week and the All-Star break and that's where you kind of mentally reset yourself. I've looked at this as an opportunity of late; there's no pressure so I can bust my butt in practice, get better and prepare myself."
