Josh Holloway Joins Tracker Season 4 as a Rival Tracker With His Own Rules

Colter Shaw is about to meet someone who knows his line of work a little too well, and something tells us these two aren't going to agree on the rules. Lost alum Josh Holloway is joining CBS's Tracker for a guest appearance in Season 4, bringing a new character into Colter's world who operates with a very different set of priorities.

Holloway will play Luke Kelsol, a fellow tracker who isn't particularly concerned about the reasons behind his assignments. Unlike Justin Hartley's Colter, who frequently gets personally invested in the people he's trying to find, Luke has a much simpler motivation: money. If the paycheck is good enough, he's interested.

Colter Shaw Meets His Opposite

According to Deadline, Luke's latest assignment becomes tangled with one of Colter's investigations, forcing the two trackers into an uneasy partnership. And if there's anything we've learned about Colter over the past four seasons, it's that working with someone who doesn't share his principles probably isn't going to go smoothly.

The setup offers an interesting opportunity to put Colter's methods under the microscope. He's certainly no stranger to bending rules or putting himself in dangerous situations, but there's usually a moral line he's unwilling to cross. Luke, on the other hand, sounds like someone who might not even see that line.

Holloway is best known for portraying James "Sawyer" Ford on ABC's Lost, a character who practically turned sarcasm and questionable decisions into an art form. His television credits also include Colony and the crime drama Duster, where he played getaway driver Jim Ellis. Bringing that experience to Tracker makes for an intriguing casting choice, particularly with a character who could challenge Colter both professionally and personally.

When Will Josh Holloway Appear on Tracker?

Holloway is scheduled to appear in Season 4, Episode 7, titled "That's the Job," airing Sunday, November 22, on CBS. His guest appearance comes as the series continues expanding Colter's world with new faces, complicated cases, and people who aren't always thrilled to have him asking questions.

Between Colter's ongoing family mysteries and his increasingly dangerous assignments, the last thing he needs is another tracker complicating his investigation. Then again, watching two men who are used to doing things their own way try to work together sounds like exactly the kind of trouble Tracker does best.

Tracker airs Sundays at 9 p.m. ET/PT on CBS, with episodes available to stream on Paramount+.
