After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed thatArizona's Derek Stepan made contact with Vegas goaltender Malcolm Subban before the puck crossed the goal line, preventing Subban from doing his job in the crease.
Therefore the original call stands - no goal Arizona Coyotes.
Since the Coach's Challenge did not result in the original call being overturned, the Coyotes forfeit their time-out.
