In late July 2026, industry reports announced that Dermot Mulroney would exit NBC’s drama Chicago Fire early in its 15th season, with his storyline set to conclude after the ~~season‑15~~ season-15 premiere on 7 October 2026. The announcement also noted the upcoming departure of original cast member Joe Miñoso and the addition of new firefighter Da’Vinchi. A few days later, at the Flashback Weekend Chicago Horror Convention, Mulroney personally confirmed the exit, saying his character would be written off after appearing in a single episode of season 15 and expressing that it was “bitter to have to leave.” He reiterated the broader cast changes, including Miñoso’s exit and Da’Vinchi’s new role as firefighter candidate Marcus Burke. ~~Together,~~ Further casting developments for season 15 include the ~~reports trace~~ addition of Matthew Daddario, who will join the ~~development from an initial network‑level casting decision~~ cast as a firefighter candidate.
