BOSTON -- A four-game road trip that began last Sunday in Washington ended Saturday afternoon at TD Garden for the Flyers in unbelievable fashion.
The Bruins scored with 5.6 seconds left in regulation on a goal from Drew Stafford that deflected off Brandon Manning to win it for Boston, 2-1.
Dave Hakstol's club finished a disappointing 1-2-1 and instead of gaining ground in the wild card, they lost it.
The crushing loss prevented the Flyers from earning a point and getting into overtime.
They began the trip three points out of the wild card and will finish at least five points behind, depending upon what the Islanders do later Saturday in St. Louis.
With the game tied 1-1 in the third, Boston showed more desperation than the Flyers. The Flyers had just one shot in 20-plus minutes.
The biggest change was moving Travis Konecny up from fourth line right wing to left wing on Valtteri Filppula's unit with Jakub Voracek. As a skill player, that's where Konecny belongs.
Voracek thought he scored off his own rebound on Tuukka Rask inside the post early in the game or that Brayden Schenn had poked it in. The no goal was upheld on review.
Bruins coach Bruce Cassidy challenged Jordan Weal's goal that tied the game 1-1 in the second period for Wayne Simmonds being offside earlier in the play and lost. That's the second time a Weal goal was challenged for Simmonds being offside and both times the goal stood.
Brayden Schenn twice had open shots in the second and third periods and fired way wide of the net.
Steve Mason played a strong game and had some difficult saves, including two ping pong pucks from David Pastrnak late in the second period from short distance.
The Flyers had a 5-on-3 for 1:43 and had some chances but Rask stood tall, denying all seven shots he faced, five of them during the two-man advantage.
After a terrible performance in Toronto, the PK units started off with five clears on Boston's first power play of the game. After the Flyers failed on their two-man advantage, the Bruins scored on their second chance on a goal from Pastrnak. He has 20 points in his last 15 games.
Matt Beleskey KO'd Manning 2:02 into the game.
Forwards Michael Raffl (knee), Dale Weise (healthy) and Roman Lyubimov (healthy); defenseman Nick Schultz (healthy).
The Flyers are off Sunday. They host the Columbus Blue Jackets Monday night at the Wells Fargo Center.
