Yellowstone has confirmed a spin-off focused on a fan-favourite character.

Variety has confirmed that CBS has officially greenlit a new series currently titled Y: Marshals, focusing on Kayce Dutton.

Luke Grimes is set to return as the former Navy SEAL and youngest Dutton sibling, who still owned a part of the family’s historic ranch after selling it.

 

 

The show won’t focus on what happens to the ranch next, but Kayce’s time at Yellowstone will still inform his character and what he gets up to.

The official synopsis reads: “With the Yellowstone Ranch behind him, Dutton joins an elite unit of US 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.”

 

 

The 13 episode season will air first on Sunday nights on CBS during the 2025-2026 midseason, as opposed to premiering on a service such as Paramount+.

CBS Entertainment president Amy Reisenbach explained that Y: Marshals is coming to a traditional channel first due to how well Yellowstone did on the network after it was added to schedules years after being on streaming.

 

 

“I think all of our shows right now are both streaming and linear,” she said. “That’s what we’re focused on, is trying to make our shows work on both platforms.

“It certainly did occur to us that the show will do really well on streaming, because all the Taylor [Sheridan] shows have. But Yellowstone and Tulsa King also did really well for us when we aired them on the network.”

SEAL Team’s Spencer Hudnut serves as creator and showrunner, while Yellowstone boss Taylor Sheridan will be an executive producer and help out when he can.

“In terms of Taylor’s involvement, we’re still early in the process,” Reisenbach added. “He’s a very busy guy, but we’ll take what we can get.”

Yellowstone’s fifth and final season, which only featured Kevin Costner for the first part, was praised by critics for how it wrapped up the hugely popular show by keeping the simplicity that fans loved.

Reviews called it “a lusty, larger-than-life soap opera that harks back to the big-haired prime of Dallas and Dynasty” (via The Daily Telegraph), and “the entertainment equivalent of a nice steak dinner – always good, always predictable, no real need to fuss with the formula” (via USA Today).
