At 5:39 of the second period in the Panthers/Kings game, Florida requested a Coach's Challenge to review whether a Los Angeles player interfered with Florida goaltender Roberto Luongo prior to Dwight King's goal.
After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed that the actions of Florida's Mark Pysyk caused Los Angeles' Nick Shore to contact Luongo 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 on the ice 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 Los Angeles Kings.
Since the Coach's Challenge did not result in the original call being overturned, the Florida Panthers forfeit their time-out.
