The rationale behind these two roster moves is quite clear. The Canadiens were carrying only six defensemen, in large part thanks to the fact that they are carrying three goalies on their 23-man roster.
With defenseman Jordan Harris dealing with an injury and currently a game-time decision for tonight’s contest against the Vancouver Canucks, the Canadiens needed an extra defenseman on their roster to provide security in case Harris can’t play.
With David Savard injured, the state of the Canadiens’ defensive depth chart leaves Lindström as the team’s seventh defenseman. So the veteran has been elevated to the NHL roster, leaving the Rocket just before their game against the Manitoba Moose.
In order to recall Lindström the Canadiens needed to clear room on their roster, and to do so they’ve sent Armia to the AHL. Armia, who cleared waivers earlier this season, was a healthy scratch for the Canadiens’ win last night over the Boston Bruins. With four goals and five points for the Rocket this season, he’d be a major addition to the Laval lineup should he dress for any games.
