After reviewing all available replays and consulting with the Referee, NHL Hockey Operations staff determined that Austin Watson's contact with Buffalo goaltender Chad Johnson was a result of the actions of the defending players.The decision was made in accordance with Note 2 of Rule 78.7 (ii) which states, in part, that the goal on the ice should have been allowed because "the attacking Player was pushed, shoved or fouled by a defending Player causing the attacking Player to come into contact with the goalkeeper."
Therefore the original call stands - good goal Nashville Predators.
Since the Coach's Challenge did not result in the original call being overturned, the Buffalo Sabres forfeit their time-out.
