Tracy Spiridakos & Jesse Lee Soffer To Reprise CHICAGO P.D. Roles For OneChicago Crossover Event

Fans of the Chicago shows are in for a treat as the OneChicago crossover event is back and scheduled to air March 4 from 8-11 p.m. ET/PT on NBC. The night will kick off with "Chicago Fire", followed by "Chicago Med", and "Chicago P.D.". Also, the OneChicago teaser promo reveals the return of two legendary "Chicago P.D." stars: Detectives Jay Halstead (Jesse Lee Soffer) and Hailey Upton (Tracy Spiridakos).

Spiridakos exited "Chicago P.D." in Season 11 of Chicago P.D., while Soffer departed the procedural show after 10 seasons. The crossover will be the first time fans will see Jay Halstead back on screen since he left Chicago to hunt down drug cartels with the Army in Bolivia. In the crossover episode, Hailey Upton returns to her former stomping grounds, but this time on the federal level as a Special Agent of the FBI. She joins her former P.D. allies after a drug enforcement task force case out of her Detroit field office leads her back to Chicago. Meanwhile, Halstead has been deep undercover, leading him on a path to the same case that Upton is investigating.

Here is the crossover event's official synopsis: "Firehouse 51 is called to an airfield when a passenger jet suddenly goes silent mid-air, triggering a high-stakes emergency. Their discovery cracks open a bigger and deadlier mystery — one with consequences that could ripple far beyond the runway and put countless lives in jeopardy".

Fresh off an extended fall hiatus, new "Chicago P.D". episodes started airing January 7, 2026 every Wednesday at 10/9c. New episodes are available to stream on Peacock Thursdays at 6 a.m. ET.

Spiridakos can next be seen in USA Network's new series "Anna Pigeon" in the lead titular role of a former city slicker who becomes a park ranger in rural Washington after a devastating loss and solves crimes that have taken place within national park grounds.
