Chicago Fire is losing some more family members.
The scorching NBC series returns for a 14th season this fall, but as is the case with any show with a long history, Chicago Fire has seen its fair share of actors hanging up their Firehouse 51 helmets over the years.
At the end of season 12, original cast member Eamonn Walker, who played Chief Wallace Boden, stepped away as a series regular, and now three more cast members won’t be returning for season 14.
Walker wasn’t the first actor to leave Firehouse 51. Jesse Spencer, a.k.a. Matt Casey, departed in season 10, but returned briefly in season 11 and again midway through season 12 for the character’s wedding to Sylvie Brett (Kara Killmer), which also served as her final episode.
Read on to celebrate the Windy City’s best fictional firehouse family members who’ve come and gone over the past 13 seasons.
1. Michael Bradway as Jack Damon
Michael Bradway, who has been part of the Chicago Fire family since season 12, playing Jack Damon, the half-brother of Kelly Severide (Taylor Kinney), will not return for season 14.
Following his Chicago Fire departure, Bradway will play Charlie in the upcoming Prime Video adaptation of Carley Fortune‘s bestselling book, Every Summer After. The series is already in production, but a release date has yet to be announced.
2. Jake Lockett as Sam Carver
Jake Lockett joined the series as firefighter Sam Carver in season 11, but left at the end of season 13.
“While I don’t exactly know what the future looks like, I do know that it won’t be exactly what it was and I am going to miss the hell out of that,” the actor wrote on Instagram in April 2025. “So much pride in this journey.”
“It’s been an honor bringing Sam to life and to every one of you, thank you for the love and support over the past three years,” Lockett added.
3. Daniel Kyri as Darren Ritter
Daniel Kyri exited Chicago Fire at the end of season 13. He joined the series as firefighter Darren Ritter in season 7, starting off as a recurring guest star before being promoted to a series regular after two seasons.
When his departure was announced, Kyri confirmed the news on his Instagram, writing, “I’ll miss this character, and it’s time to move on,” he wrote alongside a kissy face emoji. “Thank you to the cast, crew & the awesome fans.”
According to Deadline, the departures of Kyri and Lockett were “believed to be part of an effort to trim the budget.”
4. Eamonn Walker as Wallace Boden
Eamonn Walker departed the show in the season 12 finale titled “Never Say Goodbye.”
The original cast member reprised his role as Wallace Boden for an episode the following season, and when asked by PEOPLE what it was like being back on set, Walker said, “The welcoming was so warm.”
“I had missed them terribly and to find out that they had missed me as much was fantastic,” he continued. “What I didn’t realize until I left was how much everybody had left their mark on me. So it was a real pleasure to be back.”
5. Kara Killmer as Sylvie Brett
Killmer joined the show in 2014 and took her final bow in a February 2024 episode that saw the beloved paramedic marry Matt Casey (Jesse Spencer) and move to Oregon to be with him.
“The writing’s been on the wall for a long time,” Kilmer told PEOPLE at the time. “Sylvie and Matt, their saga, that relationship had been building up for three years, and then Jesse exited the show [in 2021]. … She and Matt becoming a family is for sure the most natural, inevitable conclusion for the arc of her.”
6. Alberto Rosende as Blake Gallo
Alberto Rosende joined Firehouse 51 in season 8 as Blake Gallo, a fearless firefighter candidate who had lost his entire family in a fire as a child. Toward the end of season 11, he was reunited with an aunt, and in the season 12 premiere, moved to Michigan to be closer to his newly discovered relatives.
“When I decided to end my time with Chicago, it wasn’t easy,” Rosende wrote on Instagram. “The people I’ve met were truly special, the friendships I’ve made will last a lifetime, and the story I got to tell was one that made me proud.”
7. Jesse Spencer as Matt Casey
The heroic character left Firehouse 51 — and original cast member Jesse Spencer left the series — in 2021 with the show’s milestone 200th episode, when Matt Casey moved to Oregon to become the legal guardian for the teenage sons of his best friend Andy Darden, who died in the show’s pilot.
“This was a difficult decision because I have loved the show from the start but there are other things that I would like to do in the future, and there’s some family that I need to take care of,” Spencer said. “I was marking off these milestones and looking to the future … and it was time.”
8. Adriyan Rae as Gianna Mackey
Adriyan Rae joined Chicago Fire for season 9 as paramedic Gianna Mackey, who was longtime friends with Joe Cruz. She left at the end of the season for undisclosed personal reasons.
“All I can say is we love her, and I know she’s going to be great on some other series,” showrunner Derek Haas told Entertainment Weekly at the time. “She left 51 on great terms, so there’s a chance we could check in on her. We’re always looking for something to boost up a crossover! I don’t think we’ve seen the last of Mackey in Firehouse 51.”
Rae has since starred in two seasons of The Game on Paramount+.
9. Annie Ilonzeh as Emily Foster
Annie Ilonzeh first joined Chicago Fire as Emily Foster, a former medical student turned paramedic replacing Gabriela Dawson in Ambulance 61, in season 7. At the conclusion of season 8, she reapplied and was accepted.
She has since starred in a slew of movies, including Peppermint with Jennifer Garner and Vicious Affair on Tubi.
10. Yuriy Sardarov as Brian Zvoncek (a.k.a. Otis)
After being wounded in the season 7 finale cliffhanger, Otis died heartbreakingly — and with best friend Joe Cruz by his side — in the season 8 premiere, signaling the end for original cast member Yuriy Sardarov.
“Thank you for the greatest 7 years of my life… #ChicagoFireForever,” Sardarov wrote on Instagram beside a poem he titled “Adieu” for the fallen fictional firefighter.
“I’ve known Yuriy since he was a junior in college in Michigan,” showrunner Derek Haas told PEOPLE at the time. “We did a movie together before Chicago Fire and it’s been awesome watching him develop into the actor that he is … It was tough making that call [to kill off Otis], but I knew it was right for the show. I tried to make it not meaningless.”
Otis is still frequently referenced on the show, as Firehouse 51 now has a statue in his honor outside and Cruz named his son after him.
Sardarov has since guest-starred on The Rookie and FBI: International.
