Which Tracker Stars Are — And Aren’t — Returning for Season 4 After Exits?

Justin Hartley’s Tracker has dealt with numerous surprise cast exits — so who is and isn’t returning for season 4?

The hit CBS series, which premiered in February 2024, introduced fictional survivalist Colter (Hartley) as he travels the country to help solve various missing persons cases. The ensemble cast grew with characters such as handlers Teddi (Robin Weigert) and Velma (Abby McEnany), hacker Bobby (Eric Graise) and attorney Reenie (Fiona Rene).

Weigert’s character was written off and McEnany and Graise soon followed.

“I do think it’s evolving. If I can’t evolve those characters — Randy or Reenie or Bobby — they’re not just people that just pick up the phone and go, ‘OK, here is the answer.’ That’s when the show is phoning it in,” executive producer Elwood Reid exclusively told Us Weekly in May 2025. “The challenge is when you got to learn about them, which I thought was interesting. That’s the challenge of the show is not having it fall into a formula.”

Reid noted that they didn’t want Tracker to “fall into complacency.”

“The only rule I really have of the show is each week Colter is going to come to a new place and there’s going to be a new case. How he gets those answers and what he uses on the team, that’s all something that’s up for grabs,” Reid teased. “Meeting these [local] weird characters is something we’re going to try to do more of as the season goes on. Just Colter coming in and interacting with other characters. That’s fun to see Justin flex those muscles with really good guest cast members.”

More recently, Reid weighed in on the onscreen changes. “What we’re realizing is there are characters that come on that if it worked, we’d bring them back,” he told Us in December 2025. “I do think the show can’t always do that. But when it does do that, it makes the world feel a little bit more connected.”

Reid noted there was only one constant on the show: Hartley’s fan-favorite character.

“The audience leans in because they’ve seen that character before. But I think they’re still thinking the central DNA of the show is Colter. With this guy, what makes him appealing is he is a mystery to himself,” he added. “He’s a mystery to the audience. We see him and his off time putting together some pieces of his past.”

He concluded: “I don’t know if we’ll ever put it all together, but he’s going to struggle to continue to do that. That’s just as far as we have thought. The biggest improvement we made this year — in my opinion — was getting people in the same room. Just that connectivity, I do think the audience is enjoying seeing their characters in the same place physically.”

Now that CBS has renewed Tracker for season 4, keep scrolling to see which cast members are — and aren’t — coming back:

Justin Hartley

There would be no Tracker without Colter Shaw so Justin Hartley is expected to be front and center in season 4. Hartley, however, hasn’t ruled out Colter dying in the future.

“It’s important to keep upping the stakes. I like being Colter as a hero, finding people and all that. I also really like seeing him in a suspenseful thriller and a dangerous situation,” Hartley told The Hollywood Reporter in April 2025. “I don’t want our audience to forget that this man is mortal, he’s not a superhero. He can die! The things he is doing are very very dangerous.”

Robin Weigert

After joining Tracker in season 1, Robin Weigert’s character was written off in the premiere. She isn’t expected to reprise her role in future seasons.

Abby McEnany

Season 2 caused more concern when Eric Graise was noticeably absent from six episodes. News later broke that Graise and Abby McEnany wouldn’t be coming back — at least for now.

Eric Graise

Eric Graise’s Bobby was missing from several episodes before officially being written off. There has been no word on a return and both Graise and Abby McEnany have yet to break their silence on their respective departures.

Fiona Rene

In addition to Justin Hartley, Fiona Rene is the only remaining OG cast member on the show.

“There’s going to be an attempt to build out the rest of the characters — particularly what’s happening with Reenie and where we left her off and what her life is looking like,” Reid teased to Us in August 2025. “The show always comes back to that. What makes the show work in my opinion is Colter is a guy that comes in and says, ‘I can help you.’ It works every time.”

Chris Lee

Chris Lee was brought in ahead of Eric Graise’s exit — and is expected to return.

“Having Chris Lee in the same space that Fiona Rene is in just gets you [more]. The stuff we’ve seen so far is so much fun. It has made a huge difference,” Reid told TVLine in September 2025. “Now, when Colter calls, it feels like he’s calling into something already in motion. This is all part of my ‘evil plan’ to use Fiona more — the more you can build out her world, the more the show benefits.”

Cassady McClincy Zhang

Cassady McClincy Zhang, who was introduced in season 3, will seemingly keep playing Mel in future seasons.

Jensen Ackles

Despite Jensen Ackles’ busy schedule, every season has found a way to involve the actor, who plays Justin Hartley’s onscreen brother.

Sofia Pernas

The same goes for Justin Hartley’s offscreen wife, who has played his love interest on Tracker since the show premiered.
