Chicago Fire is losing two prominent cast members as it enters its 15th season: Joe Miñoso, who has portrayed firefighter Joe Cruz since the show's early episodes, and Dermot Mulroney, who joined as Chief Dom Pascal in Season 13. These departures represent the latest chapter in a long pattern of cast changes that has defined the series throughout its run.

The specific reasons for their exits were not disclosed in official announcements, though Mulroney's character arc appeared largely resolved by Season 14's conclusion, and his work on Netflix's "The Hunting Wives" may have played a role. Complicating matters, the Season 14 finale left several plot threads hanging, particularly questions about Severide's career path, and hints suggest more cast changes may be forthcoming beyond these two departures.
