Coach's Challenge: CAR @ MTL - 0:14 of Third Period

At 0:14 of the third period in the Hurricanes/Canadiens game, Carolina requested a Coach's Challenge to review whether Montreal was off-side prior to Max Pacioretty's goal.
After reviewing all available replays and consulting with the Linesman, NHL Hockey Operations staff confirmed that the Canadiens entered the attacking zone legally prior to the goal.

Therefore the original call stands - good goal Montreal Canadiens.
Since the Coach's Challenge did not result in the original call being overturned, the Carolina Hurricanes forfeit their time-out.
