Rookie center Sean Couturier will replace Claude Giroux on the Flyers' top line Tuesday in Washington.
Giroux, the league's leading scorer, continues to make progress from his head injury, but will not make the trip, GM Paul Holmgren said. The center was injured when teammate Wayne Simmonds inadvertently kneed him in the back of the head on Saturday against Tampa Bay.
Giroux was scheduled to visit a doctor on Monday morning, but the Flyers did not release the results of any testing. Holmgren said Giroux would also see a doctor on Tuesday.
Couturier, who usually centers the fourth line, played most of the third period Saturday between Jaromir Jagr and Scott Hartnell. He will center that line Tuesday.
Giroux is also expected to miss Thursday's game in Montreal.
