Drouin (upper body) was placed on injured reserve Sunday.
In a corresponding move, the Avalanche recalled Chris Wagner from AHL Colorado on Sunday. The 29-year-old Drouin has missed the past four games. Drouin is still about a week away from being reevaluated, and an exact timetable for his return remains unclear. Ross Colton has been productive while filling in for Drouin in a top-six role.
