At 2:02 of the second period in the Ducks/Avalanche game, Colorado 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 determined that Colorado's Blake Comeau interfered with Anaheim goaltender Reto Berra before the puck crossed the goal line.
Therefore the original call stands - no goal Colorado Avalanche.
Since the Coach's Challenge did not result in the original call being overturned, the Avalanche forfeit their time-out.
