Tracker season 4 is airing on Sundays on CBS.

Actor Justin Hartley posted a rare Instagram post about the show.

The news comes amid major changes for the new season of Tracker.

Tracker is officially back for season 4—and Justin Hartley is officially back on Instagram!

The actor has been teasing promos for the CBS drama on his channel, especially as new episodes drop on Sundays. But most recently, fans got to see a more candid post from Justin as he walked around the presumed filming location.

“You ever get that feeling that we are so back?” he asked in an Instagram video on October 11. “I feel like we’re back! You know, look up, look around. We are so back! Tracker is back!”

Given how viewers have been eager to see Justin back on TV with new episodes of Tracker, they were so excited to see his post and comment on it.

“Yay! So happy it’s back on … missed it!” one person wrote in the comments. “Brilliant can't wait to watch season 4 ❤️❤️❤️,” another agreed. “Tracker is Back! Colter is back 😍,” a different follower added.

Fans know that the show has had a lot of changes over the last few months. In addition to moving from Vancouver to Los Angeles for filming, cast news has been dropping, including Jensen Ackles returning as Colter’s brother, Russell Shaw, and Justin’s wife, Sofía Pernas, coming to play Billie Matalon.

And as far as what fans can expect from the next episode (called “Original Parts” and airing on October 18), we’ll see Colter work to find a woman who went missing following an argument with her husband.

It looks very intense, to say the least.
