David Krejci and Tyler Seguin both scored in regulation and the shootout while Tim Thomas held the Flyers to one goal in the tiebreaker to ensure the Bruins caught up with the New York Rangers at the top of the East standings.

In a wild and physical see-saw struggle, Boston went 3-1 up in the first period only to see their lead disappear when Scott Hartnell exploded for a hat-trick in the second.

Krejci and Gregory Campbell responded to give the Bruins a 5-4 lead early in the third before Maxime Talbot netted the game-tying goal for Philadelphia, his second of the game, midway through the third.

The Flyers (28-14-5) had been dominated in a 6-0 defeat to the defending Stanley Cup champion Bruins (31-13-2) on December 17 but this matchup was decidedly more competitive.

The game featured 36 penalty minutes in the first period alone, including a pair of fights that set the tone for a nasty grudge match.
