CBS's hit action drama Tracker is wasting no time raising the stakes in its fourth season. Fresh off the excitement of Jensen Ackles's return as Russell Shaw, the show has now locked in another major guest star: Josh Holloway, best known for his iconic role as James 'Sawyer' Ford on Lost.
Holloway will appear in Season 4, Episode 7, which is scheduled to air on November 22. He'll play Luke Kelsol, a fellow rewardist who operates much like Colter Shaw—except his moral compass points squarely at himself. That means fans can expect a tense, morally ambiguous dynamic when these two bounty hunters cross paths.
Since its Season 4 premiere in early October, Tracker has been a ratings juggernaut, consistently ranking in the top 10 and showing no signs of slowing down. New episodes drop every Sunday on CBS and stream the next day on Paramount+. The recent return of Jensen Ackles as Colter's brother Russell Shaw gave the season an early jolt, and Ackles's scene-stealing performance has fans buzzing about what's next.
What's fueling the show's long-term momentum? A big clue is the production shift from Ontario to Los Angeles starting this season. That kind of move signals serious network commitment—and with Tracker already one of the most-watched network dramas of the 2020s, a fifth-season renewal feels like a matter of when, not if. Still, the show isn't without its challenges; some critics argue that the supporting cast needs more development, and episodes like Colter Shaw's darkest case yet show the series is willing to go to dark places.
Who Is Josh Holloway's Luke Kelsol?
According to the official character description, Luke Kelsol is a rewardist similar to Colter, but his moral compass always points to himself, not others. That suggests a clash of ethics as much as skills. Holloway's natural charisma and knack for playing roguish characters make him a perfect fit for a role that could easily become a fan favorite—or a formidable foil.
Holloway's career has been anything but quiet since Lost ended. He recently appeared in 10 episodes of Yellowstone as Roarke, the Taylor Sheridan Western that became a cultural phenomenon. In 2025, he headlined the Max original series Duster, but the show was canceled after just one season due to low viewership. Now, he's stepping into the Tracker universe, which could introduce him to an even wider audience.
What's Next for Tracker Season 4?
With Holloway's episode on the horizon and Ackles's Russell Shaw still in the mix, Tracker is stacking its guest roster with serious star power. The show's blend of procedural casework and serialized family drama continues to draw viewers, and if the ratings hold, CBS will likely keep Colter Shaw on the road for years to come.
For now, fans can catch new episodes of Tracker every Sunday on CBS and stream them on Paramount+. And if you're looking for more reasons to binge, check out why Tracker is the perfect Paramount+ binge for Reacher fans. Stay tuned for more updates as November 22 approaches.
