At 11:56 of the second period in the Hurricanes/Avalanche game, Carolina requested a Coach's Challenge to review the "Interference on the Goalkeeper" decision that resulted in a "no goal" call.
After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee confirmed that Carolina's Sebastian Aho's stick made contact with Colorado goaltender Calvin Pickard before the puck crossed the goal line, preventing Pickard from doing his job in the crease.

Therefore the original call stands - no goal Carolina Hurricanes.
Since the Coach's Challenge did not result in the original call being overturned, the Hurricanes forfeit their time-out.
