Fans of Chicago Fire will once again have to say goodbye to a familiar face as the cast of the hit NBC series continues to change before season 15 officially airs.
According to the latest reports, Dermot Mulroney, the actor who plays Battalion Chief Dom Pascal, will leave the series after appearing in the early episodes of season 15. This information comes shortly after Joe Miñoso – who has been associated with firefighter Joe Cruz since the first episode – also confirmed that he will be ending his more than a decade-long career.
Dermot Mulroney joined Chicago Fire in season 13 to succeed Wallace Boden as the new commander of Firehouse 51. Despite only being with the series for two seasons, the character Dom Pascal quickly made an impression thanks to his strict yet emotionally resonant leadership style. Personal events, particularly family tragedies, have given the character depth and become an important part of the show’s recent developments.
Sharing his decision to leave the show, Mulroney said he had a memorable time working with the crew and cast of Chicago Fire. The actor expressed regret at having to end Dom Pascal’s journey, while praising the writing team and the team’s solidarity. According to Mulroney, he will return in the season 15 premiere to complete the character’s story before officially saying goodbye to viewers.
Mulroney’s departure marks another significant transition for Firehouse 51. Previously, Joe Miñoso confirmed he would be ending his role as Joe Cruz after more than 14 years with the series. Cruz is one of Chicago Fire’s most beloved characters, so his departure is seen as closing a crucial chapter in the series’ history. However, the character will still appear in some early episodes of season 15 for a proper farewell to viewers.
Besides the farewells, season 15 also marks several behind-the-scenes changes. Producer Victor Teran will take on the role of new showrunner, while familiar faces like Taylor Kinney and Miranda Rae Mayo have been confirmed to continue with the show. Meanwhile, actor Da’Vinchi will join the cast with a completely new character, promising to bring a fresh perspective to Firehouse 51.
Despite continuous personnel changes, Chicago Fire remains one of NBC’s most successful television franchises. After many years of airing, the series maintains a stable viewership thanks to its emotionally rich stories, thrilling rescue sequences, and the strong bond between the fire crew members.
Season 15 is scheduled to air on October 7, 2026. With numerous changes both on and off camera, fans are hoping the series will open a new chapter while retaining the distinctive spirit that has made Chicago Fire so appealing over the years.
