Callahan will travel with the team to Raleigh, N.C., but coach John Tortorella said he's not sure if he'll be able to play.
Callahan is second on the team with 25 goals and hasn't missed a game this season. He was forced to sit out the Rangers first-round playoff series last year with a broken suffered from blocking a shot by Boston's Zdeno Chara in the 80th game of the regular season.
You could see out there that everybody was willing to compete, to sacrifice, even blocking shots to the end. Even in the third when we were up 5-0, guys were still working hard and blocking shots That's a nice feeling also for the future.
