Someone correct me if I am wrong, but I do not believe that we have a running back on our roster right now. We do, however, have that Michigan RB Bryson Kuzdzal, who just finished his visit to potentially help fill in that gap.
Or if the Bears somehow win both of their next 2 games against the 49ers and Lions, and the Seahawks lose of of their final 2 games against the 49ers or the Panthers. Then they may be able to avoid the Packers altogether because they would be the one seed.
