Today In NHL History - Steve Smith's Own Goal

On April 30th in 1986, rookie defenseman Steve Smith of the Edmonton Oilers accidentally played the puck off of goalie Grant Fuhr and scored on his own goal, putting the Calgary Flames ahead 3-2 in the third period of Game 7 of the Battle of Alberta Smyth Division Finals.
Smith's 23rd birthday blooper held up as the winner and Calgary took the series 4-3. The Flames would eventually advance to the Stanley Cup Finals only to lose to the Montreal Canadiens in five games.

That's today in NHL history.
