The Sabres announced during the second period that Girgensons would not return.
Buffalo defenseman Tyler Myers' shot from the right point appeared to catch Girgensons on the left side of his face as he battled for position in front of the net. Play was stopped and Girgensons was holding a towel to his face as he skated off the ice with members of the Sabres' training staff.
Girgensons, a 19-year-old who was the 14th player taken in the 2012 NHL Draft, has one assist in seven games this season.
It's cool when you think about how many great American players have played the game and the two players that were at that 18-game point streak and what they've done in their careers. It's pretty cool right now, but it was kind of overshadowed by the loss.
