Soderblom was placed on waivers Sunday, per Elliotte Friedman of Sportsnet.
Soderblom is 0-3-1 while allowing 21 goals on 133 shots in five appearances this season. If he clears waivers, he will likely be assigned to AHL Rockford. Chicago may use that roster spot to bring up Drew Commesso or Stanislav Berezhnoy.
