Pittsburgh Penguins defenseman Kris Letang was not in the lineup for the game Saturday at the Detroit Red Wings.
Letang, a Norris Trophy finalist last season, participated in the team's pregame skate, but was scratched with an undisclosed injury.
Pittsburgh is without four of its top five defensemen for the game. In addition to Letang, Brooks Orpik (concussion), Paul Martin (broken tibia) and Rob Scuderi (broken ankle) are on injured reserve.
Letang has six goals and 11 points and is minus-6 in 24 games.
