It's no secret that Chicago PD will look a little different when it returns for its fifth season.
On the outside, everything might seem the same. Voight will still be making ruthless and morally questionable decisions, Platt will probably still be hard on Burgess and Olinsky will still be rocking his signature hat.
But there's going to be quite a shake-up when it comes to the core cast. For starters, Det. Lindsay (Sophia Bush) will have accepted an FBI gig in New York. Detective Hailey Upton (Tracy Spiridakos) will take her spot in the unit and as Halstead's partner.
We'll also be seeing a familiar face. Antonio Dawson (Jon Seda) will be returning this season after a brief stint on the now-canceled spin-off Chicago Justice.
