Sidney Crosby, who was hit in the face with a puck on a deflected shot, will be out indefinitely with a broken jaw, the team announced on its website Sunday.
Crosby was struck in the face in the second minute of a 2-0 victory over the New York Islanders on Saturday. He left the game under his own power but lost several teeth and required oral surgery, the team reported.
The NHL's leading scorer, who missed all but 22 games last season and 41 games the season before with concussion problems, will require more surgery later in the week.
"Sidney Crosby underwent surgery Saturday night for a broken jaw and will be out indefinitely," Sam Kasan, director of content, reported on the website. "The Penguins will have an update on the time frame later this week."
