At 7:34 of overtime in the Sharks/Predators game, the Situation Room initiated a review under the terms of a Coach's Challenge to review the "Interference on the Goalkeeper" decision that resulted in a "no goal" call.
After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed that San Jose's Joe Pavelski made incidental contact with Nashville goaltender Pekka Rinne before the puck crossed the goal line, preventing Rinne from doing his job in the crease.
