Luke Grimes Reprises Kayce Dutton in Yellowstone Spinoff Y: Marshals

Luke Grimes is set to reprise his role as Kayce Dutton in the upcoming Yellowstone spinoff series titled Y: Marshals, which is slated to premiere midseason in 2026. The new series will follow Kayce as he joins an elite unit of U.S. Marshals, leveraging his skills as both a cowboy and Navy SEAL to deliver justice in Montana while balancing family and the psychological costs of his duty. The announcement was met with excitement from fans and fellow actors alike, with Grimes posting on Instagram, "Cowboys don't say goodbye, they say see you later." Y: Marshals continues the Yellowstone franchise's expansion, which has already seen successful prequels like 1883 and 1923, and other planned spinoffs such as 1944 and The Madison. The original Yellowstone series concluded in 2024 after five seasons, with Kayce's character having sold the family ranch under specific conditions that preserve its heritage. While details about other returning cast members remain unknown, CBS and producers highlight the show's focus on Kayce's new role and the ongoing legacy of the Dutton family.
