After reviewing all available replays and consulting with NHL Hockey Operations staff, the Referee determined that Edmonton's Caggiula pushed Bernier's glove across the goal line. According to Rule 78.5 (ix)"Apparent goals shall be disallowed by the Referee when a goaltender has been pushed into the net together with the puck after making a save."
Therefore the original call is overturned - no goal Edmonton Oilers.
Since the Coach's Challenge resulted in the original call being overturned, the Colorado Avalanche retain their time-out.
