NBC’s Chicago Fire adds Matthew Daddario to its Season 15 cast. Deadline reports that Daddario is set to join the upcoming season as a firefighter candidate. TVLine similarly confirms the casting, describing him as joining the series for the new season.

The outlets also connect the announcement to activity from the show’s cast on social media. Deadline notes that Da’Vinchi, who is already a series regular and plays a character with the same rank, shared a photo from set on August 20, teasing the new addition with fire emojis. Across the reports, the core emphasis is on Daddario’s entry and the role as a firefighter candidate, with limited additional details about his character beyond that rank match.
