Fields (ankle) is inactive for Sunday's game in Seattle, Adam Hoge of NBC Sports Chicago reports.
Fields emerged from last Monday's loss to the Vikings with an ankle injury that only allowed him to practice one time this past week. On Friday, coach Matt Nagy named Nick Foles as the Bears' Week 16 starter at quarterback with Andy Dalton (left hand/groin) ruled out and Fields' status in question. With Fields unavailable Sunday, Ryan Willis will serve as Foles' backup.
