After reviewing all available replays and consulting with the Referee, the Situation Room confirmed the "no goal" call because Nathan Beaulieu interfered with Ben Bishop prior to the puck crossing the goal line. According to Rule 78.7, "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 stands - no goal Buffalo Sabres.
Since the Coach's Challenge did not result in the original call being overturned, the Buffalo Sabres forfeit their time-out.
