Rosen will be waived Wednesday. He'll be reassigned to AHL Colorado if he clears.
Rosen recorded an assist in six games with St. Louis in 2023-24. He also provided two goals and 33 points across 68 outings with AHL Springfield. Provided he clears waivers, the Avalanche might recall him at some point during the 2024-25 campaign if they run into injury troubles.
