- The Avalanche’s AHL affiliate has announced the signing of forward Tristen Nielsen to a one-year deal. The 25-year-old became an unrestricted free agent after being non-tendered by Vancouver back in June. Nielsen spent last season with AHL Abbotsford and was a capable secondary scorer, notching 15 goals and 13 assists in 67 regular season games while chipping in with nine points in 24 playoff contests on the way to their Calder Cup title.
