At 17:01 of the third period in the Panthers/Ducks game, Anaheim requested a Coach's Challenge to review whether a Florida player interfered with Anaheim goaltender John Gibson prior to Keith Yandle's goal.

After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee determined that the actions of Anaheim's Corey Perry caused Florida's Jonathan Huberdeau to contact Gibson before the puck crossed the goal line. The decision was made in accordance with Note 2 of Rule 78.7 (ii) which states, in part, that the goal should be allowed because "the attacking Player was pushed, shoved or fouled by a defending Player causing the attacking Player to come into contact with the goalkeeper."
Therefore the original call stands - good goal Florida Panthers.
Since the Coach's Challenge did not result in the original call being overturned, the Anaheim Ducks forfeit their time-out.
