Dalton will take the first-team reps Wednesday, even though Justin Fields (ribs) is participating in practice, Adam Jahns of The Athletic reports.
Bears head coach Matt Nagy has been clear about Fields starting once he's healthy, so it's possible the rookie takes over first-team reps by the end of the week if his ribs are feeling better. If not, Dalton will get a second straight start Sunday against the Vikings, after leading the Bears to a dramatic victory over the winless Lions on Thanksgiving Day.
