EDGE Analysis

MacArthur reportedly appeared to hit the side of his head on the ice when falling down in the neutral zone, and shortly after had to be helped into the Senators' locker room. He won't return to Wednesday's tilt against the Blue Jackets. The Senators should provide an update on his status following the conclusion of Wednesday's game.
