Chicago Fire is going through several cast changes - but one actor seems to be coming back for a limited time in season 14. Daniel Kyri, who is known for his role as Darren Ritter on the NBC firefighter drama, took to Instagram on Monday, August 4, to share a selfie from set, writing, "Back! For a limited time only." Kyri, 30, was seen with costars Jocelyn Hudon and Hanako Greensmith in the photo. He shared a second behind the scenes look with David Eigenberg, Christian Stolte, Miranda Rae Mayo and newcomer Brandon Larracuente.
