At 19:33 of the third period in the Ducks/Coyotes game, the Situation Room initiated a review under the terms of a Coach's Challenge to review whether Anaheim was off-side prior to Ryan Getzlaf's goal.
After reviewing all available replays and consulting with the linesmen, NHL Hockey Operations staff determined that the puck did not leave the attacking zone at 19:13 and therefore the play was on-side prior to Anaheim's goal.

Therefore the original call stands - good goal Anaheim Ducks.

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.
