Michael Raffl suffered a concussion during Thursday's game. Raffl sustained the injury when he was struck by Colorado's Gabriel Landeskog. Flyers coach Craig Berube felt it was a clean, though obviously unfortunate, hit. Raffl will miss at least one game as a result, but given that concussions typically difficult to predict, we would be surprised if we ended up getting a firmer timetable than day-to-day.
