Luke Grimes Returns as Kayce Dutton in New YELLOWSTONE Spinoff Y: MARSHALLS Ordered at CBS

CBS is officially saddling up for more Dutton family drama, but this time, it's taking a different trail. The network has ordered a new Yellowstone spinoff centered on Kayce Dutton, with Luke Grimes reprising his role as the former Navy SEAL turned cowboy.

Titled Y: Marshals, the 13-episode series will shoot this summer and debut midseason 2026, airing Sunday nights.

Grimes’ Kayce has been a fan favorite since the very beginning. When we last saw him, Kayce had held onto a piece of the Yellowstone ranch for his family while the rest was sold to the Broken Rock Indian Reservation.

Now, Y: Marshals finds him far from the family land. The official logline reads:

“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.”

Unlike previous Yellowstone entries which premiered on Paramount Network or Paramount+, this spinoff is heading directly to CBS. According to CBS Entertainment president Amy Reisenbach:

“I think all of our shows right now are both streaming and linear. 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 shows have.

“But Yellowstone and Tulsa King also did really well for us when we aired them on the network. So, in terms of Taylor’s involvement, we’re still early in the process. He’s a very busy guy, but we’ll take what we can get.”

The show is being run by Spencer Hudnut, who previously served as showrunner on the final two seasons of SEAL Team. Taylor Sheridan will executive produce, and it’s another collaboration between CBS and 101 Studios, under the MTV Entertainment Studios banner.

This is just one of several Yellowstone offshoots in motion. Sheridan has already launched 1883 and 1923, with 1944 on the horizon. The Madison, starring Michelle Pfeiffer, is also in development, as is a spinoff focused on Beth and Rip.
