At 1:00 of overtime in the Bruins/Canadiens game, the Situation Room initiated a review under the terms of a Coach's Challenge after the on-ice officials ruled "no goal" due to interference with the Montreal goaltender.

After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed that Boston's David Pastrnak made contact with Montreal goaltender Carey Price before the puck crossed the goal line, preventing Price from doing his job in the crease.

Therefore the original call stands - no goal Boston Bruins.
NOTE: In the final minute of play in the third period and at any point in Overtime (Regular Season and Playoffs), Hockey Operations will initiate the review of any scenario that would otherwise be subject to a Coach's Challenge.
