‘Tracker’ Season 4 Cast: All the Major Stars Returning and Leaving CBS Drama

Can any show exist without its main star? Of course not! Justin Hartley is all but certain to return for Tracker Season 4. The actor will once again lead the CBS hit as Colter Shaw, the lone-wolf survivalist who tracks down missing people for rewards using his instincts. Even though the series is relocating production to Los Angeles for Season 4 after securing a major tax break, fans can relax because the move isn't changing the show's leading man. Colter Shaw is sticking around, and honestly, Tracker without Justin Hartley was never really on the table.

Fiona Rene is now one of only two original cast members still standing on Tracker. She has played attorney Reenie Greene since Season 1, serving as one of Colter Shaw's most trusted allies. There's been no word about her leaving the CBS drama, but there's no denying that Tracker has made cast shakeups almost a tradition. So, while nothing is guaranteed, fans are definitely crossing their fingers to see Reenie back for Season 4.

CBS doesn't have to come right out and say it, but we're about 98% sure Chris Lee is sticking around for Tracker Season 4. Why? Back in June, Deadline reported that Lee, who plays Randy, was promoted to series regular during Season 3. Randy first showed up in Season 2 as Bobby’s cousin, but after Eric Graise’s Bobby exited at the end of Season 3, he stepped in as Colter Shaw’s go-to tech expert. A series regular promotion is about as good a clue as it gets, so fans should expect plenty more Randy next season.

Cassady McClincy Zhang also looks like a safe bet for Tracker Season 4. She joined the CBS drama in Season 3 in a recurring role as Melanie “Mel” Day, Reenie's new assistant. So far, there's been no indication that she'll be leaving the show. That's definitely a good sign! Then again, Tracker has surprised fans with cast changes before, so you never know. For now, though, we'd say the odds are looking pretty good for Mel's return, unless the cast and producers are hiding a big surprise.

Jensen Ackles fans can breathe easy! The actor has been a scene-stealer as Russell Shaw, Colter's brother, and every appearance leaves fans wanting more. The best part? Justin Hartley already dropped a pretty reassuring update in March, telling Deadline, “I would love to bring Jensen back, and we will.” Sounds promising, right? Now we're just waiting for that return to become official because, let's face it, Tracker is always a little more fun when our favorite eye candy is around.

Eric Graise's return for Tracker Season 4 seems pretty unlikely. He played tech genius Bobby Exley from Season 1 but exited the CBS drama before Season 3. Since then, Chris Lee's Randy has stepped in as Colter Shaw's go-to tech expert, making Bobby's comeback seem even less likely. Never say never in TV, but for now, this one looks like it's off the table.

For Abby McEnany, it's pretty much the same story as Eric Graise. She played Velma Bruin, one of Colter Shaw's handlers, from Season 1 before leaving the CBS drama ahead of Season 3. Given that she hasn't appeared since then, a Season 4 return doesn't seem very likely. That said, TV loves surprises, so we're not ruling anything out just yet!
