Rozsival (shoulder) skated during Saturday's practice, ESPN Chicago reports.It's a good sign that Rozsival might be available for Sunday's game against the Penguins, but coach Joel Quenneville has yet to make an official call on the blueliner's status. Rozsival was forced to miss Friday's win over the Devils with the injury, with AHL call-up Kyle Cumiskey replacing him on the Blackhawks' blue line.
