Sixty minutes of hockey wasn't enough. The Boston Bruins and Montreal Canadiens are headed for overtime in Game 7 of their Eastern Conference quarterfinal series at the TD Garden Wednesday night, tied 3-3. 

Trailing 2-1, the Canadiens leveled things early in the second period when the Bruins' power play went from bad to worse. Not only did Boston yet again fail to score, but they gave up a shorthanded goal to Tomas Plekanec. 

The Bruins reclaimed the lead midway through the third quarter, when Chris Kelly beat Carey Price with a backhanded put-back goal on a loose rebound. But Boston's 3-2 lead would not last. 

On a power play -- Patrice Bergeron was whistled for high-sticking with under three minutes left in regulation -- the Canadiens took full advantage of the extra man as Plekanec fed a perfect cross-ice pass to P.K. Subban, who one-timed a rocket of a slapshot past Tim Thomas's glove and into the top of the net. 

The Bruins and Canadiens now head to overtime -- next goal wins the game, and the series.
