UPDATE (10/5/2025 @ 5:00 PM ET): Kayce Dutton’s Yellowstone spinoff on CBS has been confirmed. The network revealed the show’s working title, Y: Marshals , during a press event on Wednesday, May 7, in Los Angeles, in addition to when it will air during the 2025-2026 season. It’s set to be a primetime hit.

Starring Luke Grimes as his Yellowstone character, Kayce Dutton, who joins an elite unit of U.S. Marshals, Y: Marshals will be a midseason premiere on CBS and will air Sundays at 9/8c (see the full CBS fall 2025-2026 schedule here). The official synopsis says Kayce will “combine his skills as a cowboy and a Navy SEAL to bring justice to Montana, where he and his teammates must balance family, duty, and the high psychological cost of serving as the last line of defense in the region’s fight against violence,” according to Deadline.

Spencer Hudnut serves as showrunner and executive producer. Hudnut previously served as executive producer on CBS’ SEAL Team. Y: Marshals is produced by MTV Entertainment Studios with Taylor Sheridan, along with David C. Glasser as executive producers for 101 Studios, as well as John Linson, Art Linson, Hudnut, Luke Grimes, Ron Burkle, David Hutkin, and Bob Yari. The series is distributed by Paramount Global Content Distribution.

CBS president Amy Reisenbach said “we don’t do cheapskates” when asked if Y: Marshals will have the same production quality as Yellowstone. “Spencer Hudnut has run a broadcast show before,” Reisenbach said. “We have a budget for that show that’s in line with other broadcast shows.”

This is the first time Sheridan hasn’t directed a Yellowstone series. As for Sheridan’s involvement in Y: Marshals beyond a producing role, Reisenbach said, “We’re still in the early stages of the process. He’s a very busy guy, so we’ll take what we can get.”
