Like most new series, Constantine received an initial order for 13 episodes, with the hopes of getting the "back nine" order that would bring it to a full 22-episode season. That isn’t going to happen, as Deadline is reporting NBC has decided to not order any more episodes of the show for this season. However, unlike most new shows who fail to get a back nine order and are essentially being simultaneously cancelled -- including NBC's own Bad Judge and A to Z just recently -- the final fate of Constantine has not been decided.

This is an accurately reported story. Our first season is 13 eps. Next season's fate is in YOUR hands. https://t.co/Ex8bbIKQK0 #Constantine

The main difference is that Constantine debuted a few weeks later than most fall series, in late October, so the network only has five episodes of ratings to look at, even as the show is nearing completion of production on its first thirteen episodes - meaning a decision on the back nine had to be made now. Constantine has certainly had its struggles since it debuted, unable to bring in the same number of viewers at its successful NBC lead-in on Friday nights, Grimm. But the latest episode did have an encouraging +38% uptick in the ratings.Showrunner Daniel Cerone tweeted the following, after the news broke.Deadline also notes NBC has continued to promote Constantine, including using their sister channel Syfy to air a four-episode catch up marathon this week and scheduling the cast to appear at this week’s Macy’s Thanksgiving Parade broadcast. Ultimately, it seems Constantine’s future will be decided by how the remaining eight episodes do, with the final decision likely held until May.With three more scheduled for this year, there will still be five Constantine episodes left to air in early 2015, but the question then will be what NBC schedules in its timeslot on Fridays after those episodes finish up. The most obvious answer would be Hannibal, which aired Fridays at 10:00pm this past season and is now in production for Season 3. However, other possibilities include new midseason series Allegiance, Odyssey, Aquarius and a miniseries, The Slap.
