The incident happened in the third period when the puck is cleared towards forward Max Domi. Rasmus Dahlin brings up his stick in an attempt to knock it down, and as Dahlin's stick comes up, Domi not only throws his head back, but he grabs his face like he's been struck.
Dahlin was given a two-minute minor for high sticking, and fortunately, the Sabres were able to kill the penalty.
