Carter Hart acknowledged he let his frustration get the best of him Saturday night.

The Philadelphia Flyers goaltender repeatedly slammed his stick against his net after allowing six goals on 26 shots in a 6-1 loss to the Boston Bruins.

"(I) just kind of boiled over," Hart said postgame, according to NHL.com's Adam Kimelman. "I regret doing that. (I'm) not a guy who gets angry too often, but just frustrated. It was unprofessional of me to do that there at the end. So I apologize for anyone who saw that. Just heat of the moment."

The Flyers trailed 3-1 after two periods, but Brad Marchand scored twice in a span of less than four minutes early in the third and Patrice Bergeron added his second goal of the game midway through the frame to put it out of reach.

Hart is one of the NHL's best young netminders, but he's struggled early this season. The 22-year-old has allowed 14 goals over his last three starts and has given up at least four in all three defeats.
