We knew the day was coming, but we didn’t expect it would come so soon! After seven seasons playing Darren Ritter on Chicago Fire, Daniel Kyri has officially filmed his final episode of the show.

“Yesterday, I filmed my last scenes as Ritter,” Kyri revealed in a goodbye letter to the show and his character. “I’m still so amazed that my first-ever TV gig—a role that was originally meant for just three episodes—turned into seven incredible years (SEVEN?!?!! Whatttt???!) and spanned eight seasons of this iconic show! While I know I may never find another cast and crew as amazing as this one, I intend to carry what I’ve learned from you to every set in the future.”

Kyri went on to thank the team behind the show who helped create Ritter, including the writers who crafted his character’s journey over the course of the last seven seasons.

“To [Wolf Entertainment] & everyone involved in the creation of Darren Ritter, to every writer who recognized me & aligned with my intention & vision for the potential of this character, & to the fans who embraced & celebrated Ritter for every aspect of his humanity.”

He ended his farewell on an upbeat note, thanking those who have supported him and noting that he “can’t wait for you all to see what we cooked up this season!”
