Kris Letang is day to day with a lower-body injury and did not play in a 4-2 loss to the New Jersey Devils on Friday.
The defenseman did not practice Thursday and was being evaluated.
"We always feel for guys when they get banged up," Penguins coach Mike Sullivan said Thursday. "Nobody wants to go through those experiences. … It's not a nice game. People get hurt. It's just the reality of the sport that we play. We'll take each day as it comes, but we're hopeful that 'Tanger' will respond the right way, in a favorable way, for us."
Letang missed five games after having a stroke, the second of his NHL career, on Nov. 28. He has four points (one goal, three assists) in eight games since returning Dec. 10.
Ty Smith, recalled from Wilkes-Barre/Scranton of the American Hockey League on Wednesday, made his Penguins debut Friday. He was acquired in a trade with the Devils on July 16 for defenseman John Marino.
Letang, who has 16 points (two goals, 14 assists) in 29 games this season, led all skaters with 27:01 of ice time Wednesday, when the Penguins (19-11-6) allowed the Detroit Red Wings to come back from down four goals to win 5-4 in overtime. He also led all skaters with 25:48 of ice time in a 5-1 loss at the New York Islanders on Tuesday. -- Wes Crosby
