Giroux had a goal and three assists in his return from a four-game absence due to a concussion and the surging Flyers beat the Dallas Stars 4-1 Wednesday night.
"He's clearly established himself as a top player in the league," Flyers coach Peter Laviolette said. "He missed some time and wanted to get back in there. He's capable of that. It shouldn't surprise anybody."
Simmonds and Jaromir Jagr added power-play goals, and defenceman Andrej Meszaros connected at even strength for Philadelphia. Sergei Bobrovsky made 30 saves as the Flyers improved to 10-2-1 in their last 13 overall and 13-3-2 on the road this season.
Giroux, the Flyers' top scorer, was out since he was injured in a game against Tampa Bay on Dec. 10 when he was accidentally hit in the back of the head by teammate Wayne Simmonds' knee.
Michael Ryder scored in the game's first minute for the Stars, who were 4-1-0 in their previous five games.
