Chicago Fire star Eamonn Walker is set to depart the show after 12 seasons.
The actor has portrayed battalion chief Wallace Boden across the show’s run, though Deadline reports that he has decided to exit the series.
Boden’s future is set to be revealed in the upcoming season 12 finale, though he will reportedly not be killed off. Walker may also return in the future as a recurring character, the site adds.
“Boden makes a decision that impacts the race for Deputy Commissioner,” a synopsis for the finale teases. “A tense call brings up painful memories for Carver [Jake Lockett] and Damon [Michael Bradway]. Mouch [Christian Stolte] struggles to adjust to the new Truck.”
Walker isn’t the only star to depart the series recently, with actor Rome Flynn making a shock exit back in March after his character Derek Gibson left to get help for a prescription pill addiction.
Opening up about being written out, Flynn told Variety: “Just like all the fans, I was sad to see Gibson leave. He was a character I very much enjoyed playing.”

He went on to tease: “I had a wonderful experience during my time on Chicago Fire and have great respect for the cast and crew and hope to team up with Dick Wolf again when the time is right.”
Kara Killmer also recently said goodbye to the show as Sylvie Brett, with the character relocating to Portland alongside fire captain Matt Casey (Jesse Spencer).
Chicago Fire has since added Michael Bradway to the ensemble as firefighter Jack Damon, who said upon his casting: “Got to be a part of the Chicago Fire Family for season 12! Can’t wait for you guys to see it next week!”
