"Avalanche forward Peter Mueller wasn't scheduled to play in Thursday's game against the Chicago Blackhawks?. But he was expected to continue to skate with the team, yet he did not participate in Thursday's pregame skate at the Pepsi Center.

Avs coach Joe Sacco said Mueller, who missed all of last season with concussion symptoms, wasn't feeling well after Wednesday's practice and will not skate with the team today or in Saturday's game at Chicago. He has not played in the past four games, and the team finally listed him on the injured list Thursday with a "head injury.""
