"Sons of Anarchy" is not the only FX series that is coming to an end. The upcoming sixth season of "Justified" will be the last for the show and the network has shared a sneak peek to it by releasing the first teaser.

The video puts the spotlight on Timothy Olyphant's Raylan and Walton Goggins' Boyd, who will likely have a final showdown in this final installment. They seem to be friendly at the beginning, with Boyd giving his hat to Raylan, but things turn intense as the two point a gun to each other.

Goggins told EW last year, "This story is about these two people that came from a very similar set of circumstances, but one went this way and one went the other way, and yet, they're more similar than either one of them cares to admit. That's really interesting."

"When you're making a show about a small town in America, with that comes a lot of history, and what better way to serve the protagonist than to have a person that has known him since the beginning and knows his secrets, knows him that intimately," he added, explaining why his character who was supposed to be killed off in the pilot stays on the show until now.

"Justified" season 6 will premiere in January 2015. Sam Elliott and Garret Dillahunt are among new actors added to the cast.
