Michael Callahan News: Back with main roster

Callahan was called up from AHL Providence on Monday, Scott McLaughlin of WEEI reports.

Callahan's demotion to the minors Sunday appears to have been nothing more than a paper transaction. Still, the blueliner is far from a lock to suit up against the Capitals on Tuesday and will need to edge out Parker Wotherspoon or Ian Mitchell for a spot in the lineup.
