Callahan is eligible for free agency after the season, and if he doesn't reach a new contract agreement with the Rangers before two upcoming trade deadlines, he could be sent packing.
"I try not to bring that business to the rink," Callahan said. "I try to concentrate on the Rangers and what we're doing here. That's my main focus.
"That is where I want to be, on the ice playing for the Rangers."
Callahan staked New York to a 2-0 lead with goals 3:19 apart. Defenseman Anton Stralman added his first of the season in the second period, and Derick Brassard and Brad Richards scored in the third with an assist from Callahan in the Rangers' 10th win in 13 games.
Bruins 3, Canucks 1 • In Boston, After putting only five shots on goal in the first period, the Boston Bruins took aim against Vancouver goalie Roberto Luongo in the second and third.
Three of their shots got past Luongo and although only two of them counted for goals, that was more than enough offense for the Bruins to beat the slumping Canucks.
"The first period was a little bit of a tough period for us. I thought our puck management or how we move the puck around wasn't great," Boston coach Claude Julien said.
"It wasn't really sharp, but it got better in the second and third period and that made a big difference."
Boston led 1-0 after the first on Milan Lucic's goal despite being outshot 9-5. Jarome Iginla and Daniel Paille added goals in the second period for the Bruins.
