Fans of Chicago P.D. might want to brace themselves — because two of the show’s most beloved stars are teasing a surprising comeback together… but possibly on a completely different network.
After their emotional returns during the massive 2026 One Chicago crossover event 2026, actors Jesse Lee Soffer and Tracy Spiridakos have sparked major buzz among fans by revealing they would love to reunite again on screen — and this time the destination could be an unexpected CBS hit.
During a recent interview, the pair were asked about the possibility of guest-starring on the popular CBS drama Tracker, led by Justin Hartley. Instead of dismissing the idea, both stars enthusiastically said they would be completely open to it.
Spiridakos didn’t hesitate when the question came up, responding that she would “absolutely” be interested in appearing on the show if the opportunity came along. Soffer echoed her excitement and even praised Hartley, calling him a “great guy” and saying it would be a lot of fun to work together.
While nothing has been officially confirmed yet, the idea alone has already sent fans into a frenzy online. Many viewers are still obsessed with the iconic “Upstead” pairing — the fan-favorite relationship between Jay Halstead and Hailey Upton — that defined several seasons of Chicago P.D.
The two characters left the series at different times: Soffer exited the show in Season 10 while Spiridakos departed later after Season 11. Their recent return for the huge franchise crossover in 2026 marked the first time the pair had appeared together again in the One Chicago universe since their departures.
Because of that history, the possibility of seeing them reunite on another show — especially in the same episode — is incredibly exciting for longtime fans.
Interestingly, Tracker has built a reputation for bringing in high-profile guest stars throughout its seasons, making it the perfect stage for a surprise appearance. The series follows survivalist Colter Shaw, played by Hartley, who travels the country solving mysteries and tracking down missing persons for rewards.
If Soffer and Spiridakos ever joined the show, producers could even shake things up by casting them in completely different roles — perhaps as civilians caught in a dangerous case, mysterious suspects, or even villains behind a disappearance.
For now, the potential cameo remains just an exciting idea. But if CBS decides to make it happen, it could deliver one of the most unexpected TV reunions of the year — and give Chicago P.D. fans the on-screen reunion they’ve been hoping for.
One thing is certain: if Jay Halstead and Hailey Upton reunite again — no matter the show — fans will definitely be watching.
