Tyson Bagent is the immediate contingency. He replaced Williams against Minnesota and will take the first-team practice repetitions if Williams cannot work. The Bears have not announced a revised depth-chart decision or a game designation, so the practical question for the offense is how much of Johnson's plan can be shifted to Bagent while Williams begins the rehabilitation process.
The injury also changes the way Chicago evaluates the 1-1 start. The Bears opened the season with 59 points, then produced only three against Minnesota before Williams left. Johnson's next decision is less about declaring the season's direction than keeping the offense functional while the medical timeline develops.
The Bears' official news lane had no separate Monday bulletin that added a more specific timetable when this report was prepared. Chicago will have to provide that detail through practice participation and the formal injury report. Until then, week-to-week and likely to miss time are the confirmed boundaries, while a return against Philadelphia remains unannounced.
