Bush, who is coming off of CBS’ quickly-cancelled Partners, will portray Erin Lindsay, a member of the CPD investigative team who has an unexpected past.

Flueger, meanwhile, will play Kyle Ruzek, a hotheaded rookie plucked by Voight (Jason Beghe) from the Academy for dangerous, delicate undercover work for the Intelligence unit.

Fun fact: Bush and Flueger co-starred in NBC’s ill-fated Hatfields & McCoys pilot.

Chicago PD is slated to bow at midseason.
