Not all that surprising a move considering head injuries normally take at least a week or so to heal up. The interesting part is that Stefan Matteau gets another shot in the lineup and will skate on the the third line, which we'll get into either later today or tomorrow. As for Carter, the next step is whether the Devils reveal he's had a concussion or not. If they decide to eventually call it a concussion, my guess is we won't be hearing from him for a little while as the Devils will likely take him out of the locker room and allow him to heal. Concussed players are often bothered by the bright lights of television cameras and are usually told to rest as much as possible. Also, given how many unknowns there are with concussions, it's more of a wait and see process than any other injury. There won't be much of a day-to-day update, meaning there's no real reason to subject Carter to the same questions over and over again. The next time we'll see Carter might not be until next week after he's cleared to do some skating on his own.
One thing to be aware of -- concussions can sidelined players for a week or a month or a season. Look at a guy like Colorado's Gabriel Landeskog, who has missed 10-plus games already and JUST started practicing. Keep that in mind as this recovery plays out.
