Patrick John Flueger is okay and still active, but he did step away from Chicago P.D. for a while due to a personal issue and is now in the process of returning to the show.

Quick Scoop: What Happened To Patrick Flueger?

Brief overview

Patrick John Flueger, who plays Adam Ruzek on Chicago P.D. , took a leave of absence from the series in late 2025 to deal with a personal matter.

Reports linked this break to a difficult personal period that included at least one instance of alcohol use on set, though details were kept private and framed as a personal issue rather than a permanent exit.

In early 2026, coverage around Chicago P.D. confirmed that his character Ruzek was temporarily written out via an off‑screen family emergency, explaining his absence in‑universe while he remained away from filming.

Industry and fan outlets now indicate it is “just a matter of time” before Flueger is back on screen, and that he has already returned to set ahead of the holidays to resume work.

Timeline: From Leave To Return
