Williams (illness) wasn't reinstated from the reserve/COVID-19 list prior to Sunday's game against the Packers, Mark Potash of the Chicago Sun-Times reports.
After he was revealed Thursday to have tested positive for COVID-19, Williams theoretically would have had a chance to play Sunday if fully vaccinated, but the running back unsurprisingly didn't clear all health and safety protocols ahead of the Week 6 contest. Khalil Herbert is expected to serve as the Bears' lead option on the ground against the Packers while Williams is sidelined and David Montgomery (knee) is on injured reserve. Meanwhile, Ryan Nall and Artavis Pierce are on hand as depth options and could serve as change-of-pace alternatives to Herbert.
