Kayce Dutton is back — but not in the way you remember.

CBS has officially announced the premiere date for Y: Marshals, the explosive new Yellowstone spin-off that takes Luke Grimes’ beloved character into uncharted territory. Premiering Sunday, March 1, 2026, at 8 PM EST, the series promises a gritty evolution of the Yellowstone universe — with bold new faces, shocking absences, and some deeply rooted connections to the past.

🚨 From Cowboy to U.S. Marshal — Kayce’s New Frontier

Y: Marshals picks up after the emotional and violent finale of Yellowstone, where Kayce Dutton, torn between family loyalty and personal purpose, steps away from the ranch. Now, he’s trading cowboy boots for a badge, joining an elite team of U.S. Marshals in Montana.

This marks the first full-scale continuation of Kayce’s story since the flagship series ended — and it’s a major pivot. The wild land he once protected is in the rear-view mirror. What lies ahead is darker, deadlier, and more morally grey.

And if that’s not enough Yellowstone for you?

Taylor Sheridan’s second spin-off, The Dutton Ranch, is also deep into production. Starring Kelly Reilly and Cole Hauser as the fire-and-steel duo Beth and Rip, this series stays close to the original Yellowstone soil — following the couple as they raise Carter (played by Finn Little) and defend their remaining 7,000 acres.

Major names like Annette Bening, Ed Harris, and Jai Courtney are joining the cast — making it one of Sheridan’s most star-studded ensembles to date.
