BUFFALO, N.Y. (AP) - Buffalo Sabres goalie Nathan Lieuwen and defenseman Chad Ruhwedel will miss the final week of the season after being diagnosed with concussions.
Defensman Christian Ehrhoff's playing status is uncertain against Detroit on Tuesday. Ehrhoff was struck by a puck and required stitches to close a gash on his right ear.
Coach Ted Nolan provided the updates following practice Monday, a day after the three were hurt in a 5-2 loss at Philadelphia.
Lieuwen's injury means the Sabres will have to dress their seventh goalie this season.
On the bright side, Nolan says forwards Marcus Foligno, Chris Stewart and Torrey Mitchell have a chance to return to play against the Red Wings.
The Sabres (21-48-9) have four games left and are guaranteed to finish in last place.
