What is checked in a "video review" by officials in the NHL?

In the NHL, a "video review" is primarily focused on examining potential errors related to goals, major penalties, and other significant calls that can influence the outcome of a game. This process involves the on-ice officials reviewing video footage to ensure that decisions regarding goals—such as whether the puck completely crossed the goal line, whether there was goaltender interference, or if the goal was scored in accordance with the rules—are made accurately.

Additionally, major penalties that may have game-changing implications can be scrutinized to confirm their legitimacy. The ability to review these critical moments helps maintain the integrity of the game, ensuring that crucial calls are correct and fair.

The other options, while relevant to the NHL in their own right, do not involve video reviews conducted by officials. Player trades are transactions between teams, team penalties are assessed in real-time during a game, and player injuries are managed by medical staff rather than through video analysis during gameplay. Thus, the focus of video review is distinctly on clarifying pivotal decisions that arise during the course of a match.
