Couturier sustained a lower-body injury in the first period of Game 3 on Thursday, but did not look restricted in the morning skate Sunday, took line rushes in pre-game warm-ups in his usual spot, between forwards Maxime Talbot and Eric Wellwood.
Couturier, the eighth pick of the 2011 Entry Draft, has three goals and an assist in nine playoff games, but has developed into the team's best defensive center.
"Sean is an important piece of the team," Flyers coach Peter Laviolette said following the team's skate Sunday morning. "He looked good skating out there. He's smiling, that's always good."
Here's how the lineup will look when the puck drops about 7:30 p.m. ET:
Well, for me this one's concerning, the way we performed. Because three games in, playing a desperate team on the road, I was expecting something else than this. Right now, I'm just disappointed. The other games, I thought we did some things that you can build off your game. There wasn't a lot accomplished in tonight's game.
