The Avalanche placed Wagner on waivers Thursday, Elliotte Friedman of Sportsnet reports.
The Avalanche are expected to activate Valeri Nichushkin from suspension ahead of Friday's game versus Washington. A move was needed to free up a roster spot, and Wagner was the odd man out. Wagner had a goal in 12 games with the Avs this season and will likely be sent to AHL Colorado, should he pass through waivers.
