Devils coach John Hynes confirmed after the team’s morning skate at Rogers Place here in Edmonton that left wing Marcus Johansson did suffer a concussion in Wednesday night’s 2-0 win at Vancouver. He is out indefinitely. Johansson went hard into the boards on his first shift of the game as he chased Canucks rookie Brock Boeser, who veered to his left as Johansson continued face first into the backboards just 57 seconds into the game. A woozy Johansson was attended to on the ice then skated slowly under his own power to the Devils bench before being led to the team’s dressing room for evaluation.
