Chicago Firelost one of its main stars,Jesse Spencer, after he exited the show during season 10,and while losing his character was painful, the actor’s next project might make up for the heartbreak. The NBC procedural drama is heading into its thirteenth season in late 2024 and has lost many actors and actresses over the course of its 12-year run. With any series that runs for that long, the cast is bound to change. Spencer himself was a part of the originalChicago Firecastas he began playing Matt Casey during the pilot episode in October 2012.
Chicago Fireseason 13 will reportedly contain 22 episodes and premiere on Wednesday, August 16, 2025, at 9 p.m. ET on NBC.

Casey started as a lieutenant and the Truck 81 leader inChicago Firebefore he was promoted to captain in season 6. Throughout his time on the NBC show, Casey went through many ups and downs. He got married, divorced, and then married again. Nevertheless, it was easy to empathize with Spencer’s character andlove Casey from early on inChicago Fire. As a result, Spencer’s exit was painful for many, even with the actor making a few guest appearances in seasons 11 and 12. Now,Casey is seemingly gone for good, and Spencer has moved on to his next series.
