Update: Sean Couturier has made a quick recovery from a leg injury and is expected to play in New Jersey on Sunday night.
The rookie center took part in the morning skate. Officially, the Flyers say he will be a game-time decision.
Defenseman Andrej Meszaros has been ruled out for tonight.
Rinaldo says he won't 'cross the line'
If Zac Rinaldo replaces the injured Sean Couturier in the Flyers' lineup Sunday night, it will be his first appearance since Game 4 against Pittsburgh.
"If I'm in there, I'm going to play within the rules and not cross any lines and just play hockey," Rinaldo said.
Rinaldo, who finished second in the NHL in penalty minutes this season, said the Flyers will "have more fight" because they are in a 2-1 series hole.
The Flyers' power-play ineffectiveness has played a huge role in the series.
In the first round, the Flyers were 12 for 23 (52.2 percent) on the power play against Pittsburgh; they are 2 for 16 (12.5 percent) in this series.
"We have to adjust and be better," Brayden Schenn said.
In two overtime power plays Thursday, the Flyers had a total of one shot.
"Obviously we did really well against the Penguins. The Devils saw that and they studied it and they're killing well," Max Talbot said. "They're blocking shots and they're sacrificing their body. They have a good PK, and we have to find a way to score."
The Flyers did not have a three-game losing streak (excluding shootouts) all season. They have lost the last two.
