"Chicago Fire" has received some good news, with NBC ordering one extra episode, reports Deadline.com. That will bring its freshman season to 23 episodes, the story notes.
The Dick Wolf-produced drama series has been a late bloomer, with an October debut and a slow start in the ratings. It held onto its lead-in, though, and performed well enough to receive a back-nine order.
The show reached series highs earlier in January, the piece adds.
