The Bruins came out with the early energy and dominated the Flyers in the opening minutes of Game 1 of the Eastern Conference semifinals and lead 2-0 after 20 minutes.
The only bit of bad news was an apparent right knee injury to Marco Sturm .
Sturm will not return to Game 1 after colliding with Philadelphia’s Matt Carle along the offensive corner boards in the first two minutes of the first period and apparently banging his right knee.
He was helped off the ice by teammates Patrice Bergeron  and David Krejci . Sturm’s replacement, Steve Begin, scored the game’s first goal, his first in 30 playoff games. The goal came at 2:39 of the first.
Bergeron, who assisted on Begin’s goal, scored one of his own when he put a collected a loose rebound offered up by Brian Boucher  on Dennis Wideman’s slap shot from the right point. Bergeron’s flipped it past Boucher for a 2-0 lead at 12:54.
Both goals were even strength and both were the result of lots of traffic in front of Boucher. No penalties in the first.
The Bruins outshot the Flyers, 15-8, in the opening period.
