Crosby, 25, has been sidelined since March 30 when he was hit in the face with a puck. He underwent surgery to repair a broken jaw and have major dental work done.
He has missed the last 11 games, but the Penguins still locked up the top seed for the NHL Eastern Conference playoffs, which begin Tuesday. There was no timetable announced for Crosby's return to the lineup.
He scored 15 goals and had 41 assists in 36 games this season. Even with his lengthy absence, Crosby's 56 points are second-most in the NHL this season.
Crosby missed 41 games at the end of the 2010-11 season and the first 20 games of the 2011-12 season because of a concussion.
