News of a third series is unlikely to be announced until after the series has wrapped up in the UK.
Judging by the renewal pattern of the first two seasons, fans could hear news in May 2020 or towards the end of the year.
The Rookie received a series order in October 2017 and premiered in October 2018.
In November 2019, The Rookie was picked up for a full season of 20 episodes and in May 2019, ABC renewed the series for a second season.
