Joe Miñoso is set to leave NBC’s Chicago Fire during Season 15, bringing an end to a long run on the firefighter drama. The actor has been part of the series since Season 1, making his departure a notable change for one of NBC’s established franchise shows.

The exit means Firehouse 51 will lose one of its veteran firefighters, according to the report. Because Miñoso has been with Chicago Fire from the beginning, the move stands out as a significant cast change for a series that has built much of its appeal around long-running characters and team dynamics.

Chicago Fire is produced by Wolf Entertainment and Universal Television, and Miñoso’s departure comes as the show heads deeper into its run. While the trimmed report does not include full details about how the character will be written out, the Season 15 exit is expected to reshape part of the ensemble.

For viewers, the news signals the end of an era for one of the drama’s original cast members. As Chicago Fire continues, Miñoso’s departure is likely to be one of the key story developments surrounding the upcoming season.
