The One Chicago fandom is in absolute meltdown after explosive rumors began circulating online suggesting that NBC may already be preparing for a future without longtime Chicago Fire star Taylor Kinney. And now, even more shocking speculation has emerged — with internet chatter wildly linking Hollywood stars Tom Holland and Austin Butler to a possible “next-generation” Squad 3 storyline.
The rumors erupted after several recent episodes noticeably reduced Kinney’s screen time, reigniting fears that Kelly Severide could eventually leave Firehouse 51 for good. Fans immediately flooded social media with theories, emotional reactions, and panic-filled predictions about the future of one of the franchise’s most iconic characters.
While there is currently no official confirmation that Kinney is permanently exiting Chicago Fire, speculation has continued growing due to the actor’s previous leave of absence and recurring rumors surrounding his long-term future on the show.
Some fans believe NBC could eventually introduce a younger Hollywood-style replacement to refresh Rescue Squad 3 and attract a new generation of viewers. That’s where the names Tom Holland and Austin Butler suddenly entered the conversation.
“Imagine Austin Butler walking into Firehouse 51 as the new Squad leader,” one viral post read. “The internet would literally explode.”
Another fan wrote: “Tom Holland in One Chicago? I’d watch every episode instantly.”
Neither actor has been linked officially to the franchise, and no credible reports suggest either star is actually negotiating for the role. Still, that hasn’t stopped the online frenzy from spiraling into full-blown speculation territory.
The possibility of losing Severide remains deeply emotional for longtime viewers. Since Chicago Fire premiered in 2012, Kinney has become one of the central pillars of the series, with Kelly Severide evolving into arguably the show’s most recognizable firefighter. His chemistry with Stella Kidd, his leadership in Squad 3, and his emotional storylines helped define the franchise for more than a decade.
Previous reports confirmed that Kinney temporarily stepped away from the show in 2023 due to a personal matter, sparking widespread concern among fans at the time.
More recent coverage has emphasized that the actor is not currently confirmed to be leaving permanently, despite renewed fan anxiety over his absences.
Still, that hasn’t slowed the wildfire rumors.
Entertainment forums, TikTok edits, and Facebook fan pages are now packed with mock posters imagining Austin Butler or Tom Holland wearing CFD gear beside Firehouse 51 veterans. Some viewers are excited by the idea of injecting younger Hollywood energy into the franchise, while others insist nobody could ever replace Severide.
“One Chicago without Taylor Kinney wouldn’t feel the same,” one emotional fan posted. “There is no Squad 3 without Severide.”
For now, NBC has made no announcement regarding any casting shakeups involving Chicago Fire. But if there’s one thing the online reaction proves, it’s this: the mere thought of replacing Taylor Kinney has already sent the fandom into complete chaos.
