Weiss (groin) skated on his own prior to Friday's morning session, MLive.com's Ansar Khan reports. Weiss had been limited to off-ice activity since injuring his groin nine days earlier, so the fact that he's resumed skating suggests he's starting to notice some improvement. After he takes part in a few practices with the team, the Red Wings are expected to send Weiss back to AHL Grand Rapids to finish off the conditioning assignment that was previously interrupted by the injury.
