Situation Room Initiated Challenge: CAR @ COL - 3rd

At 19:50 of the third period in the Hurricanes/Avalanche game, the Situation Room initiated a review under the terms of a Coach's Challenge to examine whether Colorado was off-side prior to Nathan MacKinnon's goal.
After reviewing all available replays and consulting with the linesman, NHL Hockey Operations staff confirmed the Avalanche entered the attacking zone legally prior to the goal.

Therefore the original call stands - good goal Colorado Avalanche.

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.
