General manager Ron Hextall suggested Coburn's lower-body injury was more than a day-to-day concern, Renaud Lavoie of TVA Sports reports. Coburn was spotted using crutches prior to Thursday's game, so it certainly seems like a long-term absence could be in store. The Flyers haven't offered any information regarding how he sustained the injury, but he did appear to be in some pain after taking a puck to the foot from the Bruins' Torey Krug on Wednesday night. If he's indeed sidelined for multiple weeks, the Flyers' already-suspect blue line could be in some trouble.
