Luke Grimes Kicks Off New ‘Yellowstone’ Spin-Off Without Taylor Sheridan – First Look Revealed md06

Yellowstone may have ended, but the Dutton story is far from over. CBS has dropped a sneak peek (via ET) at Y: Marshals, the latest series set in Taylor Sheridan’s Western universe — though this time, Sheridan himself is not directly involved. The spinoff follows Luke Grimes’ Kayce Dutton as he sets out on a new path far from the Yellowstone Ranch, trading his cowboy hat for a Marshal’s badge.

Set after the events of Yellowstone’s final season, Y: Marshals sees Kayce leaving behind his role as Montana’s Livestock Commissioner to join an elite team of U.S. Marshals. The official synopsis teases that Kayce will “combine 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.”

Grimes isn’t going it alone. Returning from Yellowstone are Brecken Merrill as Tate Dutton, Gil Birmingham as Thomas Rainwater, and Mo Brings Plenty as Mo, Rainwater’s right-hand man. Noticeably absent (for now) is Kelsey Asbille, who played Kayce’s wife, Monica. However, a wedding ring seen on Kayce’s hand in the teaser suggests the couple’s story may not be over just yet.

Joining the new cast are Logan Marshall-Green (And Just Like That…) as Pete Calvin, one of Kayce’s old military friends, Arielle Kebbel as Belle, Tatanka Means as Miles, Ash Santos as Andrea, and Brett Cullen in a recurring role as Harry Gifford, the head of the U.S. Marshals in Montana.

What Other Yellowstone Spin-Offs Are Coming Out?

Y: Marshals is just one piece of the ever-growing Dutton saga. Paramount Network also has several related projects in the works, including The Madison, about a New York family adjusting to Montana life, The Dutton Ranch, which reunites Kelly Reilly, Cole Hauser, and Finn Little as Beth, Rip, and Carter, and Sheridan’s next prequel 1944, along with a new series set at the Four Sixes Ranch in Texas. So yeah, if you want more yeehaw with guns, you won’t have far to look.

For now, though, all eyes are on Kayce Dutton as he saddles up for a new kind of frontier — one with a badge, a new team, and ghosts of the past still riding close behind.

Y: Marshals will premiere on CBS as part of the network’s midseason 2026 lineup, airing Sundays at 9/8c.
