BOSTON – The Boston Bruins continued to struggle offensively against a Philadelphia Flyers team that had allowed 40 goals entering Tuesday night’s game at TD Garden.

The Bruins had plenty of ice time in the offensive zone but were unable to solve Flyers goalie Samuel Ersson, who made 22 saves for his first shutout of the season as Boston fell 2-0.

The power play was once a deadly weapon, but lately it’s become more of a blackout.

Boston had four power-play opportunities, including a five-on-three at 1:37, but managed only two shots on Ersson. The Bruins had good puck movement and kept the puck during almost all of the man advantages, but let shots slip by on numerous occasions.

Bruins head coach Jim Montgomery tried to spark the offense by mixing up the forwards late in the second period to start the third.

Brad Marchand joined David Pastrnak on the top row with Elias Lindholm, and Pavel Zacha dropped to the second row to join Charlie Coyle. Montgomery also moved Mark Kastelic from the fourth line to skate with Coyle and Zacha, while Morgan Geekie took Kastelic’s spot.

The new combinations didn’t help much as the Bruins managed just two shots on net through 16 minutes of the third period.

If Joonas Korpisalo hadn’t been paying attention to the Bruins’ pipes, the game could have gotten out of hand early.

Korpisalo, starting in only his third game of the season, made two excellent saves in the opening seven minutes to keep the match scoreless. His only mistake came in the middle frame when Tyson Foerster beat him five-hole for the first goal of the match.

The Bruins’ backup netminder made 17 saves in his second loss of the season.

Boston will look to get back in the win column when they travel to Carolina to take on the Hurricanes on Thursday night. The Lenovo Center Puck Drop is scheduled for 7:00 PM ET, and you can watch all the action, following an hour of pregame coverage, on NESN.
