One day after the Philadelphia Flyers expressed optimism that the injury keeping Claude Giroux off the ice was not a concussion, the team announced that its star will be sidelined indefinitely with a concussion.

"Claude reported not feeling very good today," general manager Paul Holmgren said in a statement. "Over the past few days, his symptoms have gradually gotten worse. He will be out indefinitely with a concussion."

The team had released statements saying Giroux was feeling better each day, but the center met with doctors on Tuesday and the prognosis was not good. 

The NHL's leading scorer, Giroux leads the Flyers in goals (16), assists (23) and points (39). Rookie Sean Couturier took Giroux's spot on the first line during practice on Monday and is expected to do so during Tuesday night's game against the Washington Capitals.
