Y: MARSHALS (working title) (Premieres Sundays, Mid-Season, 9:00-10:00 PM), stars Luke Grimes as Kayce Dutton. With the Yellowstone Ranch behind him, Dutton joins an elite unit of U.S. Marshals, combining his skills as a cowboy and Navy SEAL to bring range justice to Montana, where he and his teammates must balance family, duty, and the high psychological cost that comes with serving as the last line of defense in the region’s war on violence.

With Yellowstone’s final ride now complete, Luke Grimes isn’t done with the Dutton legacy just yet. The actor is set to reprise his role as Kayce Dutton in Taylor Sheridan’s upcoming CBS spin-off, Y: Marshals — a series that shifts the spotlight to a team of U.S. Marshals operating in Montana.
The story was first reported by MovieWeb, whose coverage continues to track the evolving Yellowstone universe.
For longtime fans of Kayce, this pivot marks a major evolution. From his early days as a conflicted rancher to a man torn between family loyalty and personal conviction, Kayce’s journey has always been one of quiet intensity. Now, combining his skills as a cowboy and former Navy SEAL, he’ll be stepping into a world where justice is murky, loyalty is tested, and every decision carries weight.
Grimes has confirmed that “familiar faces” will join him in Y: Marshals, though no additional cast members have been officially announced. While Matthew McConaughey has been confirmed for a Yellowstone spin-off, his involvement in Y: Marshals specifically has not been confirmed.
Set to premiere in spring 2026, Y: Marshals will be part of CBS’s midseason lineup — expanding Sheridan’s universe while giving Kayce Dutton a new frontier to navigate.
Hollywood Outbreak will be following this story closely — because when legacy shifts, we listen.
