What was supposed to be a day-to-day injury for Valtteri Filppula likely will drag through this week. Bothered by a left shoulder injury, Filppula has missed the last three games and coach Mike Babcock doesn't anticipate having the forward back this week. "He's working out and he skated by himself (Monday), which is a positive thing," Babcock said. "I don't expect him this week." Just returning to the ice Monday was a nice change for Filppula. "Little bit of puckhandling, no shooting yet," Filppula said. "I was out there a little bit. It didn't feel too bad, but I could still feel it. But it's getting better." What's working against Filppula this week is the schedule. It'll be important to see how Filppula looks in a full-scale practice, but there are games Tuesday (Colorado), Thursday (Edmonton) and a back-to-back with Columbus on Saturday and Sunday. The lone practice looming is Friday, as the Wings have a day off Wednesday. "That's the frustrating thing," Filppula said. "You don't miss that much time but you miss a lot of games. Today was the first day I felt better, good enough to go out there and skate a little bit, and I'm happy about that."
