The move doesn't come as much of a surprise as the Lions' offense has taken major steps back this season, despite a roster full of offensive weapons. Stay tuned for more news as it becomes available.
The Lions have already made a decision as to who will fill the vacated roles in the interim:

According to Dave Birkett, a decision has not been made about play-calling, but expect Jim Caldwell to take the reigns.
