Michael (illness) was a non-participant at Thursday's practice, Rob Demovsky of ESPN.com reports.
Fortunately for Michael, his illness has arrived mid-week and not on the verge of game day. Nevertheless, Friday's injury report will shed light on its severity. With James Starks unable to practice due to a concussion, the Packers may be relying on Michael and Ty Montgomery (shoulder) to fuel the rushing attack Sunday in Chicago. Head coach Mike McCarthy may have tipped his hand during media availability Thursday, though, telling Ryan Wood of the Green Bay Press-Gazette that Montgomery is a candidate to approach 20 carries in a game.
