At 13:36 of the second period in the Islanders/Ducks game, Anaheim requested a Coach's Challenge to review whether New York interfered with goaltender John Gibson prior to Mathew Barzal's goal.
After reviewing all available replays and consulting with the Referee, the Situation Room determined that New York's Cal Clutterbuck interfered with Gibson, preventing him from doing his job in the crease. The decision was made in accordance with Rule 78.7 (ii), which states in part: "The standard for overturning the call in the event of a "GOAL" call on the ice is that the NHL Situation Room (which shall include a former referee in the Officiating Department in the decision-making process), after reviewing any and all available replays and consulting with the Referee who made the original call, determines that the goal should have been disallowed due to "Interference on the Goalkeeper," as described in Rules 69.1, 69.3 and 69.4."
Therefore the original call is overturned - no goal New York Islanders.
Since the Coach's Challenge resulted in the original call being overturned, the Anaheim Ducks retain their time-out.
