Luke Grimes Will Lead Yellowstone’s CBS Spinoff, Marking a Big Shift for the Hit Franchise

Kayce Dutton’s Story Moves to Network TV as Y: Marshals Becomes Official on CBS Fans of Yellowstone won’t have to say goodbye to Kayce Dutton anytime soon. CBS confirmed Luke Grimes will return in a new spinoff tentatively named Y: Marshals. The show is set after the Yellowstone series finale and will build on the lasting popularity of Taylor Sheridan’s Western saga. Unlike earlier spinoffs that went back in time, Y: Marshals continues the Dutton family’s saga in a modern setting, this time filtered through the lens of law enforcement.

The Plot: Kayce Dutton Swaps Ranching for Marshal Duty in Montana

In Yellowstone’s last episode, Kayce made a huge decision by selling much of the family’s land, closing one chapter of ranch life. Now, Y: Marshals picks up after these events and flips Kayce’s story in a new direction. Instead of dealing with family cattle and old feuds, Kayce steps into the world of US Marshals. The series will spotlight his skills as both a ranch hand and a Navy SEAL. CBS describes his new journey as combating crime in Montana as part of an elite team. This career move means new dangers and alliances. The official description says Kayce will have to balance his commitments at home with the risks of his work—a theme familiar to long-time Yellowstone viewers but set against different challenges. While Grimes returns as Kayce, CBS has not shared many character details. Still, it’s reasonable to expect that Kayce’s wife Monica (played by Kelsey Asbille) and their son Tate could return for this new chapter.

Taylor Sheridan at the Helm, Spencer Hudnut as Showrunner

Like the original, Taylor Sheridan will serve as executive producer. Sheridan’s approach to character-driven Westerns has won fans over since the start, and his continued involvement signals more of the tense, grounded storytelling Yellowstone is known for. Spencer Hudnut, previously of SEAL Team, will act as showrunner, which hints at a blend of military and procedural drama. The spinoff comes from MTV Entertainment Studios and 101 Studios, mimicking the production style that helped Yellowstone stand out on cable and streaming. Other familiar names, including John Linson, Art Linson, and David C. Glasser, will also serve as executive producers. Luke Grimes, now an executive producer himself, takes a more active role behind the camera.

Release Details: CBS Brings Yellowstone Universe to Broadcast Audiences

Y: Marshals is scheduled to premiere midseason as part of CBS’s upcoming lineup, currently set for Spring 2026. Airing on a major broadcast network changes the game for Yellowstone’s expansion. The mainline show found much of its fanbase through cable and streaming platforms like Paramount+, but the move to CBS will open Kayce’s story to new audiences. CBS plans to air the show on Sunday nights, a prime slot often reserved for its top dramas.

What This Means for Yellowstone’s Future: Multiple Spinoffs in the Works

Y: Marshals is just one part of a broad strategy to keep the Yellowstone universe moving. Other projects are in development, including spinoffs with favorites like Beth and Rip (“Dutton Ranch”), and a show starring Michelle Pfeiffer and Matthew Fox called The Madison. 1944, another prequel, is also planned. These new projects are a direct result of the original show’s success. Yellowstone wrapped up in late 2024 after five seasons, but Taylor Sheridan’s writing has left plenty of threads to pick up. The surrounding stories will keep Western fans invested in the Dutton family for years.

What Fans Should Expect: A Shift From Ranch Life to High-Stakes Law Enforcement

Y: Marshals offers something different while staying true to the roots of Yellowstone. Expect less cattle-wrangling and more investigations, as Kayce’s skills transfer from the range to the difficult world of law enforcement. The decision to center the series on Marshals instead of ranch hands might refresh the franchise, especially with Grimes anchoring the cast. The personal drama that defined Kayce’s character will likely remain front and center, but now with the added pressure of working on both sides of the law. The Bottom Line for Yellowstone Fans CBS is betting big on Y: Marshals as the next chapter of Yellowstone. With Luke Grimes at the center, the spinoff gives Kayce Dutton fans a reason to stick with the universe. Sheridan’s involvement and CBS’s primetime commitment suggest the network sees Y: Marshals as a cornerstone of its future drama lineup. Viewers looking for more family-driven conflict and Western themes will find plenty to like, but don’t be surprised if the show pushes Kayce in new—and more dangerous—directions than ever before.
