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.
He's, believe it or not, actually one of my favorite guys, and I've ended up trading him twice. I appreciate what he's done. He was one year away from being an unrestricted free agent, and I felt with this opportunity, that it was a chance that we were able to get somebody for him in Nick Bonino and Adam Clendening.
