Replay showed Colin Chaulk scored late in the second period, but there was an odd event that happened. Rapid City defenseman Michael Couch got knocked down on the back of the goal before the shot went in. The shot bounced off Couch's backside and out of the net where the Komets put it in again. Now, because Couch was situated against the back of the net the way he was, there was no way the goal judge or the referee could see the puck inside the net to confirm it from either angle. Couch was blocking their view.
We've had no official ruling on why the goal was ruled off, however.
