UPDATE: May 10, 4:47 p.m. EDT -- ABC isn’t letting go of the Nathan Fillion-led series just yet. On Friday, “The Rookie” was renewed by the network for Season 2, according to TVLine.

Original story: ABC’s “The Rookie” ends its freshman run on Tuesday with its Season 1 finale, but there’s a chance the episode could double as a series finale.

The network hasn’t chosen to renew or cancel the Nathan Fillion-led cop drama yet, which means its fate is still up in the air. After starring on ABC’s “Castle” for eight seasons, Fillion’s a fan-favorite on the network, which could help the show get a Season 2.

Ratings-wise, “The Rookie” isn’t a clear winner or loser. Out of nine ABC dramas, it’s coming in at number five, both in demo, with an average of a 0.73, and viewers, with an average of 4.169 million.

Luckily, whether the show’s renewed or not, fans still have at least one more new episode to enjoy. Season 1, episode 20, titled “Free Fall,” airs Tuesday night and follows the cops at a turning point in their careers.
