"Neither Danny Briere nor James van Riemsdyk practiced Wednesday with the Flyers at Skate Zone.
Both are recovering from concussions; both participated Tuesday with the team at the morning skate and both practiced on Monday.
General manager Paul Holmgren said their absences could be interpreted as a setback, though a source said that in Briere's case, he simply wanted more rest as not to push his recovery.
"The fact that they weren't out there today, I guess you could call that a setback, I don't know," Holmgren said. "We're dealing with concussions. They didn't feel as good today as yesterday. I'm not sure what that means.""
