Boston forward Nathan Horton's goal with 10:42 left in the game made it 4-2, Toronto. Then, linemate Milan Lucic popped home the rebound of a shot, closing the gap to 4-3 with 1:22 left in regulation. Finally, center Patrice Bergeron completed the historic comeback with just over 50 seconds remaining when his wrist shot beat Leafs goalie James Reimer, tying the score at four goals apiece.
Lucic, a Boston fan favorite due to his physical play on the ice, attributed the comeback to perseverance.
"It seemed like we started to play more reckless and taking pucks to the net and things like that. It was just like, (forget) it and leave everything on the line and hopefully everything will take care of itself," Lucic told NHL.com.
Bergeron capped off the magical night by collecting a loose puck in the Toronto end and sliding the puck past Reimer just over six minutes into the overtime period, giving the Bruins the series win, four games to three.
The Bruins will now meet the New York Rangers in the NHL's Eastern Conference semifinals. New York staged its own comeback in a quarterfinal series against the Washington Capitals, being down three games to two, by winning both Games 6 & 7 on consecutive nights.
