EDGE Analysis
Considering the Bruins have not recalled another goaltender, it's probably safe to assume that the injury isn't significant enough to keep him from playing in an emergency situation. It wouldn't be surprising if the veteran is back in goal for Tuesday's contest against the Red Wings, but Anton Khudobin receives the starting nod Saturday.
