At 2:04 of overtime in the Golden Knights/Canucks game, the Situation Room initiated a review under the terms of a Coach's Challenge to determine whether Golden Knights forward Brandon Pirri interfered with Canucks goaltender Jacob Markstrom prior to the puck entering the net.

After reviewing all available replays and consulting with the Referee, NHL Hockey Operations staff confirmed the Referee's call on the ice that Pirri interfered with Markstrom before the puck crossed the goal line.
Therefore the original call stands - no goal Vegas Golden Knights.
