Yellowstone Universe Rides Into CBS With Kayce Dutton Spinoff ‘Y: Marshals’

Luke Grimes will reprise his role as Kayce Dutton in one of seven new series on the network’s slate for next season.

The world of Yellowstone is getting a new outpost — and a new network.

CBS has ordered a spinoff of the hit western as part of its 2025-26 slate. Currently titled Y: Marshals (with the “Y” standing for Yellowstone, naturally), the show will star Luke Grimes, who will reprise his role as Kayce Dutton from the flagship series as he joins an “elite unit of U.S. Marshals, combining his skills as a cowboy and Navy SEAL to bring range justice to Montana,” per the show’s logline. It’s set to premiere in spring 2026 and is one of seven new series the network will roll out next season.

Spencer Hudnut (SEAL Team) will be the showrunner on Marshals, executive producing with Taylor Sheridan, John Linson, Art Linson, Grimes, Ron Burkle, David Hutkin and Bob Yari. As with all the Yellowstone-verse series, the show comes from MTV Entertainment Studios and 101 Studios.

The network’s rookie class also includes dramas Boston Blue, CIA and Sheriff Country — all of them spinoffs of current or recently ended CBS shows (Blue Bloods, FBI and Fire Country, respectively); a single-camera comedy called DMV; and unscripted shows The Road, America’s Culinary Cup and Harlan Coben’s Final Twist, a true-crime series hosted by the best-selling author.

CBS has also rearranged some of its veteran series, moving FBI from Tuesday to Monday nights (where it will pair with CIA) and creating a three-hour NCIS block on Tuesdays. The latter move brings NCIS, entering its 23rd season in the fall, back to the night it anchored the first 18 of those seasons. NCIS: Origins and NCIS: Sydney will follow at 9 and 10 p.m.

Sheriff Country, starring Morena Baccarin, will lead into Fire Country on Friday nights, and Boston Blue — which will follow Mark Wahlberg’s Danny Reagan to a new city — gets the 10 p.m. slot that Blue Bloods called home for virtually its entire run.

In its schedule announcement Wednesday, CBS also planted a couple of seeds for the 2026-27 season. FBI and Ghosts are on multi-year orders that will take them through 2026-27. The network will also have Einstein, a procedural starring Matthew Gray Gubler that it initially ordered for next season before deciding to push it back a year. Additionally, the network has opened a writers room and ordered 12 scripts for Cupertino, a “David vs. Goliath” legal drama set in Silicon Valley from Elsbeth and Evil creators Robert and Michelle King.
