Weiss was sent to AHL Grand Rapids on a conditioning assignment, MLive.com's Brendan Savage reports. After appearing in just 26 games in his first season in Detroit due to a sports hernia, Weiss has been a healthy scratch in all but one the Wings' eight games this season. Since ice time has been hard to come by with the parent club, Weiss will simply head to Grand Rapids for games Wednesday and Friday as a means of staying fresh for when the Red Wings might ultimately need him. Weiss will rejoin the Red Wings in Buffalo for their game Sunday, and remain on the Red Wings' 23-man roster through the duration of his stay with Grand Rapids.
