New images from the upcoming One Chicago crossover event have surfaced online, and unfortunately for Chicago P.D. fans, they appear to confirm the franchise’s biggest worry regarding one key character’s participation.
There had been optimism that Adam Ruzek — played by Patrick John Flueger — might return in time for the 2026 One Chicago crossover. Fans noticed that Flueger had recently been seen back on set after taking a break from the show earlier in the season for personal reasons, leading many to hope Ruzek would rejoin his old team for the crossover event.
However, none of the newly released crossover photos include Ruzek, making it clear that he won’t be part of the crossover story. Instead, the pictures feature the rest of the Chicago P.D. cast alongside returning favorites such as Jay Halstead and Hailey Upton, who are both set to make their long-awaited comebacks.
This absence is especially disappointing for fans because Ruzek has been missing from several recent episodes, and although the show finally addressed his absence on-screen — explaining that he was taking time off to help his ailing father — there’s still no sign of when the character will return.
Despite this, the crossover event is shaping up to be a big reunion for many cast members, and fans are excited to see familiar faces from across the One Chicago universe unite in the crossover’s storyline.
