‘Chicago PD’: Here’s Why Brian Geraghty Left the Show

by Taylor Cunningham

After only two seasons with Chicago PD, Brian Geraghty announced he was leaving the series. But why?

The actor first appeared in the One Chicago franchise back in 2014, when it was in its sophomore season. In the show, he played Detective Sean Roman, a series regular who eventually became romantically entangled with Kim Burgess.

But in 2016, Roman unexpectedly left the Windy City for San Diego after he was shot on the beat. And, of course, the move marked the end of Brian Geraghty’s run on Chicago PD.

Because most fans didn’t see the write-off coming, they assumed something terrible had happened behind the scenes. But according to The List, the reason for the exit was neither dramatic nor surprising. Geraghty simply moved on with his career.

Geraghty Was Working on a Year-to-Year Basis with ‘Chicago PD’

Apparently, creator Dick Wolf wanted to cast Brian Geraghty as Officer Roman so much that he agreed to forgo the usual seven-year contract stipulation he puts on the other actors. So Geraghty was allowed to work on a year-to-year basis.

“[Geraghty] had a lot of choices, and we courted him and pitched him what the show could be,” producer Matt Olmstead told TV Line. “And we were crossing our fingers that we’d get him … He was like, ‘I don’t know if I can commit to a seven-year contract. This sounds great, but I’ve got to take it year by year,’ which Dick doesn’t do very often. But the deal was made.”

And because he walked into the job in a way that left his options open, the cast and crew weren’t exactly surprised when he opted to leave after two years.

However, Olmstead told The Hollywood Reporter that the actor’s exit was very professional. And Geraghty left the show on good terms.

“[He] called like a gentleman and said, ‘Hey, I got these other things going on. I feel like I’ve done my thing, and I’m just giving you a heads up that I’m going to go pursue those things,'” Olmstead explained to Distractify. “All told, fans got the chance to know Officer Roman and Wolf got to work with his actor of choice. It sounds like everything worked out for the best.”

And though Brian Geraghty handed over his badge in 2016, he still made one more appearance in Chicago PD. In a 2020 episode titled Burden of Truth, the actor reprised the role of Sean Roman after his on-screen sister became a missing person.

These days, you can catch Geraghty starring as Ronald Pergman in another procedural drama, Big Sky. However, in his new role, he flipped from playing a good guy to playing a sinister villain. And as fans of the series would agree—the character transition was seamless.
