The Belfast Giants' 3-3 Challenge Cup draw with Edinburgh Capitals ended in confusion as the match officials were unaware that overtime was to be played to decide the winner of the game.
Elite League officials must now make a decision about how the matter will be resolved following the game in Belfast.
Craig Peacock, Mitch Ganzak on the powerplay and Colin Shields were the scorers for the Giants.
Craig McCallum, Ryan Hayes and David Rutherford were on target for Capitals.
The sides will meet again in an Elite League fixture on Saturday night.
