Kelly Reilly (Yellowstone) Announces Pregnancy With First Child At Age 46 md20

The spinoff, which continues after the events of Yellowstone season 5, is one of several spinoffs currently in the works. Fan-favorite duo Beth Dutton (Kelly Reilly) and Rip Wheeler (Cole Hauser) are also getting their own spinoff for Paramount+, titled The Dutton Ranch, for Paramount+. Although that doesn’t have a release date, Kayce’s return is not far behind.

Y: Marshals will premiere on CBS on Sunday, March 1, 2026, at 8 PM ET. The night begins with 60 Minutes at 7 PM ET. It’ll then be followed by the series premiere of Y: Marshals. The hit third season of Tracker shifts to 9 PM while Watson’s season 2 ends the night at a new time at 10 PM ET.

Y: Marshals focuses on Kayce as he puts the Yellowstone Ranch behind him to join an elite unit of U.S. Marshals. Grimes’ character combines his skills as a cowboy and his past to bring range justice to Montana. He will also have to balance family, duty, and the high psychological cost that comes with his job. The main cast for the spinoff has been confirmed, with Logan Marshall-Green (Upgrade, Spider-Man: Homecoming) playing Pete Calvin, a friend from Kayce’s time in the military.

It’s likewise been reported that Brecken Merrill, Gil Birmingham, and Mo Brings Plenty will reprise their Yellowstone characters. Merrill plays Tate Dutton, Kayce’s son, with Birmingham and Mo Brings Plenty as Thomas Rainwater and Mo, respectively. They’ll be joined in the cast by Arielle Kebbel (The Vampire Diaries), Tatanka Means (Ransom Canyon), Ash Santos (Mayor of Kingstown), and Narcos alum Brett Cullen.

Kebbel portrays Belle, Santos appears as Andrea, and Means plays Miles, all characters who are U.S. Marshals. Cullen has the role of Harry Gifford, the authoritative Montana chief guiding the Marshals’ work in his capacity as the Head of the U.S. Marshals in Montana. It’s a shift from what Yellowstone audiences have come to recognize about Kayce, albeit not a completely fresh slate, since there will be some familiar actors returning alongside Dutton to bridge the gap between the two shows.

Spencer Hudnut, who previously worked on the CBS and Paramount+ drama SEAL Team, will also serve as showrunner of Y: Marshals. The new show may remind viewers of the long-running David Boreanaz series, which dealt with similar themes, but the spinoff carries strong Yellowstone connections off-screen. Franchise creator Taylor Sheridan is among the executive producers, as are David C. Glasser, John Linson, Art Linson, Ron Burkle, David Hutkin, Bob Yari, Grimes, and Hudnut.
