Peterka suffered an upper-body injury in the first period Saturday versus New Jersey and will not return. Peterka took a big hit from Brenden Dillon in the neutral zone and stayed down for a while before leaving the ice. Dillon received a minor for interference and a five-minute major for fighting after Alex Tuch came to the defense of Peterka. The Sabres will leave Prague after the game and more information may not be available until Buffalo returns home. Peterka started the game on the top line, alongside Tage Thompson and Tuch. Peterka was replaced by Jordan Greenway.
