Another Yellowstone spinoff is confirmed to be in the works by CBS.
The network is developing a procedural in which Luke Grimes, 41, is set to reprise his role as Beth Dutton’s younger brother Kayce Dutton, per Puck.
CBS is already working on a spinoff that will follow Beth Dutton, who is portrayed by Kelly Reilly, and Rip Wheeler, who is played by Cole Hauser.
In the spinoff starring Grimes, Kelsey Asbille and Brecken Merrill are expected to join the new father-of-one, reprising their respective roles as Kayce’s wife Monica and their son Tate.
Taylor Sheridan’s Yellowstone franchise includes two prequel series, 1883 and 1923, as well as sequel series The Madison, which stars Michelle Pfeiffer, Patrick J. Adams and Matthew Fox.
Grimes previously worked alongside Yellowstone star Kevin Costner from 2018 to 2024 until the latter’s character John Dutton was killed off in a November 2024 episode of the original series.

Costner was abruptly written off the show when he acrimoniously exited the show over scheduling conflicts with his Western movie franchise Horizon.
The show continued for another month before Yellowstone wrapped, ending with its fifth and final season.
For another month after Costner’s exit from the series, Grimes said they did not talk to each other amid rumored ‘tension.’
‘I haven’t talked to him since,’ he told Men’s Health in December 2024. ‘It’s not a case of any hard feelings or anything; it’s just, he’s Kevin Costner.’
Laughing, he added: ‘He’s a big deal. I do have his phone number — I just don’t feel like it’s my place to reach out. He can reach out to me if he wants to.’
‘None of us saw it coming the way it did, and obviously there was news about possible blowups behind the scenes or whatever,’ he continued.
‘But just, like, in life, man, these things happen. They happen fast and they’re not predictable.’
Then, he compared Costner’s sudden exit to how he couldn’t have anticipated his father’s death many years ago.

He added: ‘I lost my father a few years ago. It happened fast, and it was not the way that you would think that that would happen. In life, these things happen and then people have to start making decisions. And in our little Yellowstone world, that helped ramp the show up into a boil.’
At the time, he said that Costner’s decision not to return after nearly eight years instilled a ‘finality’ to Yellowstone.
‘Him not coming back felt like, “Okay, we’re going to have to land this plane now for real,’ he told People in November 2024.
‘I think the patriarch leaving was always going to be part of the story. That’s always where it was headed, like, “What do these kids do? What does this family do when their rock is gone?”‘
