The Penguins will be without captain Sidney Crosby.
For how long they are not sure, though there is optimism he could be ready for the Stanley Cup playoffs, which begin April 30.
Crosby had oral surgery after he was struck in the face with a puck on Saturday in a win over the New York Islanders at Consol Energy Center. He played only one shift.
Crosby was diagnosed with a broken jaw, which required the surgical procedure. A time frame for his recover is not know, but the Penguins anticipate having one later this week.
Crosby had not missed a game this season. He is the NHL leader with 56 points.
The Penguins have won 15 straight games. They play host to Buffalo on Tuesday.
