Apparently when the ref flagged the bears for having 12 men on the field they made the correct call after the challenge.
It does not matter that the Bear player got off the field before the snap, 12 men on the field is a penalty as soon as a snap is imminent. What the ref did wrong is that he should of stop the play before it even started.
