Explanation: First, video review determined that Sean Monahan's shot at 3:41 (16:19 elapsed time) completely crossed the Philadelphia goal line.
Philadelphia then initiated a Coach's Challenge for goaltender interference, which determined that Monahan interfered with Cart Hart by pushing his pad, which caused the puck to enter the net. The decision was made in accordance with Rule 69.7, which states in part, "In the event that a goalkeeper has been pushed into the net together with the puck by an attacking player after making a stop, the goal will be disallowed."
