His first career NHL goal snapped the Flyers from lethargic to lively and gave Konecny a good reason to call home.
''My mom's probably going to cry on the phone,'' he said.
Voracek returned after a spell on the bench and his presence gave a boost to the Flyers.
''He's a tough guy. Don't tell him I said that,'' Giroux said.
Konecny scored early in the third period for the Flyers.
Moulson scored both goals in a three-goal second period that chased Flyers goalie
The Flyers were listless in their third game in four nights and were soundly booed off the ice at the end of the second.
Those jeers turned to cheers by the time Voracek knocked in Philly's second shootout goal.
Moulson had his first two-goal game since Dec. 11, 2014 against Calgary and has four goals this season. He had eight in 81 games last season.
The Sabres had the last four days off and were clearly sharper early than the Flyers. The Flyers had 10 giveaways through the first two periods and Giroux's boarding penalty early in the second sparked Buffalo to two straight goals.
''We played some bad hockey today,'' Giroux said. ''We know we're a better team than this. Our work ethic kind of got us in the game.''
Battling for the puck behind the net, Giroux plowed his left shoulder into
Moulson's second power-play goal of the game - and league-high fourth of the season - sent Neuvirth to the bench.
Mason stopped eight shots and two more in the shootout.
''Guys have a belief that you get one, more are going to come,'' Mason said. ''TK got us going.''
The Flyers got a needed lift in the third when Konecny scored his first career goal. The 19-year-old forward was Philadelphia's first-round pick in the 2015 draft and is one of the hopeful cornerstones for the rebuilding franchise.
''He's been buzzing all season long,'' Giroux said.
The Sabres lamented a big blown opportunity to earn two points.
''It's on us to be better,'' Sabres captain
Nilsson, who stopped 49 of 50 shots in two preseason games, was solid until the late collapse in his first start of the season.
''I felt like I saw the puck well and I felt like I made some good saves,'' Nilsson said.
