With the game tied and under three minutes to go, Dylan Demelo accidentally high sticked teammate Adam Lowry in the face, but because he was near, it was Ryan Nugent-Hopkins that faced the penalty that could have cost the Oilers the game.
Fortunately for the Oilers, this one wouldn't cost them on the back of the Hyman overtime winner, but in the future, this could prove very costly for a team, so the NHL coming in with this rule was a fantastic choice.
