Beaulieu will miss at least a month due to a lower-body injury, Sara Orlesky of TSN.ca reports.
Beaulieu was injured in Tuesday's matchup with the Avalanche after blocking a shot. The blueliner is far from an offensive stud -- he's registered just four helpers in 21 games -- but his absence could expose netminder Connor Hellebuyck to more rubber. In Beaulieu's stead, the team will call up a player from the minors, with Cameron Schilling and Sami Niku likely atop the list. Once a decision on who to promote is finalized, Beaulieu figures to be placed on injured reserve.
