MAY 24, 1988/OILERS vs. BRUINS
Before Edmonton could turn out the lights on the Bruins, a power failure struck 59-year-old Boston Garden, causing the only midgame postponement in playoff history. The Oilers had just finished celebrating Craig Simpson's goal to tie Game 4 of the finals 3-3 with 3:23 to play in the second period when a 4,000-volt switch overloaded, causing the building to go dark. After a half-hour delay, the match was postponed by NHL executives. Game 4 was replayed in its entirety in Edmonton two nights later, and the Oilers completed a series sweep with a 6-3 win for their fourth Stanley Cup in five years.
