Pittsburgh Penguins captain Sidney Crosby is listed as day-to-day after suffering a mysterious injury in Thursday's 4-1 loss to the Phoenix Coyotes.
As per team policy, the Penguins did not disclose details of Crosby's injury, and its unclear if he will be able to play Saturday night against St. Louis
The Penguins have a pre-game skate before taking on the Blues, and the team said Crosby's availability for the game will depend on how he feels.
Crosby played only two shifts in the third period against the Coyotes before leaving the game. He did not return.
It's unclear what happened to Crosby. Television replays showed the Penguins forward skate to the bench. He sat down with a grimace before heading back to the locker room.
"Honestly, I don't even know what happened; I'd have to look at the tape," Crosby told reporters after the game. "I just had some discomfort. I just decided in the third period I couldn't do much."
Crosby ranks second in team scoring with 13 points (three goals, 10 assists) in 11 games this season.
