Rozsival, who suffered an apparent leg injury during Thursday's Game 4 game against Minnesota, could be out for an extensive period of time. In response to a question after the Game 4 victory over the Wild, Hawks' coach Joel Quenneville said that 'it doesn't look good' in terms of Rozsival's injury. He suffered the injury in the second period and could not put much weight on his left leg while leaving the ice. With the Blackhawks' sweeping the Wild in the series, there will be a few days off for the team before starting the Stanley Cup Western Conference finals. There will be more known about how long Rozsival will be out with an MRI on Friday.
