Get ready, folks: The Yellowstone universe isn’t done yet, and it’s back with a vengeance! Y: Marshals, the next chapter in the Dutton saga, is ready to bring a whole new brand of high-stakes justice to the wilds of Montana. And now, CBS has finally released details on who’s riding alongside Kayce Dutton this time around.

Of course, Luke Grimes is returning as Kayce Dutton, but this time he’s swapping ranch life for a badge. Y: Marshals picks up after the final season of Yellowstone, with Kayce Dutton leaving the ranch behind to join a specialized U.S. Marshals unit in Montana. The Taylor Sheridan series follows the elite team as they confront crime on the frontier.

Joining him are some familiar faces from the original Yellowstone series. Gil Birmingham, Mo Brings Plenty, and Brecken Merrill are all reprising their roles, underscoring the idea that family drama still runs deep—even with Kayce now focused on law and order instead of wrangling cattle.

But it’s not just old friends riding into town. The spinoff is also introducing a roster of new characters who promise to bring extra grit to the series. Arielle Kebbel will play Belle, a steadfast U.S. Marshal, while Ash Santos joins as Andrea, another marshal keeping things steady on the frontier. Tatanka Means takes on the role of Miles, rounding out the marshal team. Brett Cullen steps in as Harry Gifford, the head honcho of the U.S. Marshals in Montana, and Logan Marshall-Green will play Pete Calvin, an old military buddy of Kayce’s who is sure to complicate his story even further.

There’s one notable absence: Monica Dutton. Kelsey Asbille’s name has yet to be confirmed on the cast list, even though her on-screen son Tate (played by Merrill) is set to return. So, where’s Monica, and what does her absence mean for Kayce’s journey?

Luckily, fans won’t have to wait too long to find out. Y: Marshals is set to premiere in spring 2026 as a mid-season CBS drama airing Sundays at 9 p.m. ET. The spinoff series will run for 13 episodes—and is already shaping up to be one wild ride!
