Joe Miñoso leaves “Chicago Fire” after 15 seasons, a source confirms to Variety.

The actor has played firefighter Joe Cruz on the NBC drama series since season 1. He will appear in several episodes of the show’s upcoming 15th season to conclude his character arc.

Miñoso appeared in the pilot of “Chicago Fire” and recurred in the first season as a guest star before being promoted to series regular in season 2. He was one of four original “Chicago Fire” cast members who remained on the long-running drama, alongside Taylor Kinney, David Eigenberg and Christian Stolte.

Miñoso’s departure comes as “BMF” star Da’Vinchi joins “Chicago Fire” as a new firefighter at Firehouse 51. Season 15, premiering Oct. 7, also welcomes a new showrunner, Víctor Terán, who replaces Andrea Newman after 14 seasons.

In the season 14 finale, Joe Cruz’s wife is rushed to the hospital for a pregnancy complication, which turns out to be just a small blood vessel problem. Joe, who had previously told his colleagues at Firehouse 51 that he wanted a third baby, discovers that he and his wife are expecting twins. The season ends on a cliffhanger, as several fan-favorite firefighters rush into a burning storage facility with no visibility. As the roof threatens to collapse, it is unclear if all the characters will make it out of the building safely.

“Chicago Fire” returns Oct. 7, sandwiched between its sister shows “One Chicago,” “Chicago Med” (starting in season 12) and “Chicago PD” (season 14).
