The National Hockey League has used video review for years to determine plays such as goaltender interference and whether a puck crossed the goal line. In recent years the NHL has implemented additional reviews for offside as well. This was then expanded to reviewing both major penalties and high sticking plays.
Currently when it comes to high sticking, officials are only allowed to review double minors to ensure that it was the stick of an opposing player that caused the damage. Unfortunately though this doesn't cover plays where blood isn't drawn.
Last season during the playoffs these changes would have allowed the Maple Leafs to review a play, which ultimately cost them Game 7 against the Lightning. In the 3rd period, Maple Leafs' forward David Kampf was called for a high stick late in the game, which never actually struck Cal Foote in the face.
