Why Did Roman Leave Chicago PD? His Exit Explained

Officer Sean Roman quickly became a core member of the cast of Chicago PD after joining the Dick Wolf show in season 2 ― but only made it to season 3 before leaving the series. Roman, played by Brian Geraghty, underwent a lot of character development in his short time on the show, but his exit meant a lot more potential went unfulfilled. However, Roman wouldn’t have been able to continue in his police role after a season 3 episode took a dramatic turn ― and outside the show, actor Geraghty had a good reason to say farewell, too.
