Erik Karlsson scored a goal and dished out two helpers for the Senators in a 5-4 overtime loss to the Canadiens Thursday. With 45 points in 48 games this season, Karlsson has continued to score at the pace he set for himself over the past two seasons. Clarke MacArthur also enjoyed a nice game with a goal and an assist in the losing effort. Bobby Ryan and Kyle Turris each found the back of the net as well.
