Sam Ersson kept the game within reach early, as the Flyers tied things up in the third and defeated the Vancouver Canucks in a shootout in Friday night's season opener.
The Flyers have won seven of their last eight games since the holiday break and get a test in the NHL's leading team, the Boston Bruins, on Monday afternoon.
The Flyers enter Thursday's game in a four-game losing streak though, and now get the test of facing the NHL's best team in the standings. The Boston Bruins come in with a 14-2-0 record and wins in four straight games.
Two goals in the third period extended the Boston lead to a 5-2 margin, the final from Wells Fargo Center as the Flyers closed out a three-game homestand.
The Boston Bruins come to town, playing in just their second game of the season. For three Flyers, it will mark their first game in the Orange and Black.
