Callahan, who is considered day-to-day, suffered the injury Monday night against the New Jersey Devils, but was not forced to leave the game. Newly acquired John Scott will take his place in the lineup.
Callahan has 25 goals this season, second-most on the team.

We need to get back to work and we'll start to do that tomorrow.
