The Boston Bruins raised their 2011 Stanley Cup banner on Thursday.

But the Philadelphia Flyers dropped the curtain on the celebration.

Ilya Bryzgalov stopped 22-of-23 shots in his Philly debut and Jakub Voracek tallied the deciding score late in the first period as the Flyers edged the defending champions, 2-1, in the season opener for both clubs at TD Garden.

Claude Giroux also registered a first-period goal for the Flyers, who suffered a four-game sweep at the hands of Boston in last year's Eastern semifinals.

Brad Marchand notched the lone score for the Bruins, who couldn't sustain the momentum from a lengthy pregame ceremony which honored the club's first title since 1972.

Tim Thomas, the reigning Vezina Trophy and Conn Smythe Trophy winner, made 27 saves in defeat.
