Injuries to defensemen, including Brian Campbell, who is expected to miss 7-8 weeks with a fractured clavicle and rib after being hit by the Washington Capitals' Alex Ovechkin, forced Byfuglien to skate at his old defenseman position.
Defenseman Nick Boynton, recalled from Rockford after the injury to Campbell, also took to the ice for the first time as a Blackhawk. Boynton will wear No. 24.
Also not on the ice for practice was goaltenders Cristobal Huet.
