Fans of the expansive “Yellowstone” universe have a new series to look forward to, with Luke Grimes set to reprise his role as Kayce Dutton in a spin-off currently titled “Y: Marshals.” This project marks a significant development as it’s the first Yellowstone project not solely created by Taylor Sheridan, though he will still be involved as an executive producer.

Here’s everything we know about the “Yellowstone: Marshals” series:

What is “Y: Marshals” about?

The series will pick up after the events of the main “Yellowstone” series finale, which saw Kayce Dutton make the pivotal decision to sell the Yellowstone Ranch land to the Broken Rock Reservation. With his ranching days seemingly behind him, “Y: Marshals” will see Kayce join an elite unit of U.S. Marshals in Montana.

The official synopsis reveals that Kayce will “combin[e] 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.” This suggests a shift from the family drama focus of Yellowstone to a more procedural, action-oriented narrative, while still retaining the Western essence.

Who is involved?

• Luke Grimes will headline the series, reprising his fan-favorite role as Kayce Dutton.
• Spencer Hudnut, known for his work on SEAL Team, is taking the helm as the writer, director, and executive producer. This is a notable departure from Taylor Sheridan being the sole creative force.
• Taylor Sheridan will still serve as an executive producer, maintaining a connection to the broader Yellowstoneuniverse he built.
• While not officially confirmed, it’s highly anticipated that Kelsey Asbille will return as Kayce’s wife, Monica, and Brecken Merrill as their son, Tate, given that Kayce’s family will remain a crucial aspect of his character’s journey.

When will it be released and where to watch?

• “Y: Marshals” is slated for a mid-2026 premiere.
• It will air on CBS Sunday nights at 9 PM ET. This is a significant move, as the main Yellowstone series aired on Paramount Network, and other prequels like 1883 and 1923 stream on Paramount+. This means Y: Marshals will be the first Yellowstone universe project to be a CBS original network show.
• The first season is expected to consist of 13 episodes.

Filming Details:

• Production for “Y: Marshals” is scheduled to begin in Summer 2025.

Why is this spin-off happening?

The expansion of the Yellowstone universe has been a clear strategy for Paramount and Taylor Sheridan. With the main series concluded, continuing the stories of beloved characters like Kayce Dutton allows the franchise to evolve while maintaining its dedicated fanbase. The shift in creative leadership for this particular spin-off indicates a desire to explore new angles and perhaps broader genres within the established world. Luke Grimes himself has expressed excitement about the new chapter, posting on Instagram: “Cowboys don’t say goodbye, they say see you later.”

“Y: Marshals” joins a growing slate of Yellowstone universe projects, including the prequels 1883, 1923, and the announced 1944, as well as other spin-offs like 6666 and The Madison. This new series promises to offer fans a fresh perspective on justice in the modern American West, seen through the eyes of a familiar and complex Dutton.
