Alex Chiasson didn't see his tiebreaking goal go in Thursday night. Neither did Dallas Stars coach Lindy Ruff. More important, the referees didn't see the puck hit the net. At the other end of the ice, though, Stars goalie Kari Lehtonen saw the goal scored, and stopped the puck when it came to him. On review, the goal was ruled good. That started Dallas toward three goals in barely a minute and a 5-1 victory over the Calgary Flames.
