Grimes (pictured) will reprise his role as Kayce Dutton from 2018’s Yellowstone and join an “elite unit of U.S. Marshals, combining his skills as a cowboy and Navy SEAL to save Montana on the wild side,” according to the series description. The series is scheduled to premiere in spring 2026 and is one of seven new series the network will debut next season.
Spencer Hudnut (Seal Team) is the showrunner for Y: Marshals and will serve as an executive producer alongside Taylor Sheridan, John Linson, Art Linson, Grimes, Ron Burkle, David Hutkin and Bob Yari.
CBS’s newest series also include the dramas Boston Blue, CIA and Sheriff Country — all spinoffs of current or recently ended CBS shows (Blue Bloods, FBI and Fire Country, respectively); a single-camera comedy series called DMV; and unscripted series The Road, America's Culinary Cup and Harlan Coben's Final Twist, a true crime series hosted by the bestselling author.
CBS has also reshuffled some of its old shows, moving FBI from Tuesday to Monday nights (where it will air alongside CIA) and creating a three-hour slot for NCIS on Tuesdays. The latter move returns NCIS, which will begin its 23rd season in the fall, to the night it aired for its first 18 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 follows Mark Wahlberg’s Danny Reagan to a new town — will take the 10 p.m. slot that Blue Bloods called home for most of its run.
The network will also have Einstein , a procedural starring Matthew Gray Gubler, which it initially ordered for next season but decided to postpone for a year. In addition, the network has opened a writers room and ordered 12 scripts for Cupertino, a Silicon Valley-set legal drama from Elsbeth and Evil creators Robert and Michelle King.
