NHL general managers propose minor rule changes, including expanded coach's challenges for video reviews on certain infractions.

NHL general managers have proposed several minor rule changes at their annual meetings in Florida, including an expansion of coach's challenges to include video reviews for puck-over-the-glass calls and "friendly fire" high-sticking infractions, provided a penalty is already called. These changes must go through the NHL's competition committee and the league's Board of Governors for final approval.
