Situation Room Initiated Challenge: DET @ BOS - OT

At 4:12 of overtime in the Red Wings/Bruins game, the Situation Room initiated a review under the terms of a Coach's Challenge to examine whether Boston was offside prior to David Pastrnak's goal.
After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed no offside infractions occurred before the puck crossed the goal line.

Therefore the original call stands - good goal Boston Bruins.
