The Penguins said on the team website Sunday that Crosby had surgery Saturday night, and there will be an update on his status later in the week.
Crosby, the NHL's leading scorer, was struck in the face with a puck in the first period of the Penguins' 2-0 win on Saturday. The team said Crosby also had ''major dental work'' and will have more work done later in the week.
The Penguins have won 15 straight games. They next play Buffalo on Tuesday.
