"The Ottawa Senators were sailing along, playing well and sitting on a 3-1 lead, when all of a sudden their world turned upside down.

The Boston Bruins scored three unanswered goals in just 7:44 from the end of the second to early in the third to take the lead and hang on for a 4-3 win.

The worst goal was the fourth — a shot from the centre red line from Dennis Seidenberg that was going wide but which took a weird bounce and deflected in off Craig Anderson's stick.

Zdeno Chara, Milan Lucic, and Brad Marchand also scored for Boston.

Colin Greening, Kyle Turris, and Erik Karlsson scored for Ottawa.

Tim Thomas faced 33 shots for the Bruins while Anderson faced 30."
