Allen (lower body) will be out for at least a week, Eric Engels of Sportsnet.ca reports.

EDGE Analysis

This will rule Allen out for Thursday's tilt with Chicago, as well as at least Montreal's next two games. The veteran netminder was injured during Wednesday's loss to Boston. While he's out, Samuel Montembeault and Cayden Primeau will handle the goaltending duties. Per CapFriendly, Allen was also placed on injured reserve.
