Jensen Ackles is officially back to filming season 3 of Justin Hartley's Tracker after the show lost multiple cast members. Ackles, 47, took to Instagram on Wednesday, July 30, to share a video of him on set, saying, "Good to be back in action." The actor encouraged TV fans to watch the newest episode of his Prime Video series Countdown while they await for him to "eventually down the road" reunite with Hartley, 48, on Tracker. His return comes after Eric Graise, who played Bobby in the first two seasons, and Abby McEnany, a.k.a Velma, both departed the hit CBS show.
