Tucker will appear in the FX drama's final five episodes

The final season of FX's Justified is adding a Kingdom player.

Kingdom star Jonathan Tucker has joined the final season of Justified, The Hollywood Reporter has learned.

Tucker — who recently began filming his role on the drama — will appear in the final five episodes of the FX series as Boon, a hired gun of Katherine Hale's (Mary Steenburgen) ex, Avery Markham (Sam Elliott). He joins Elliott and Garret Dillahunt as season six's notable new foes.

Justified creator Graham Yost told THR that Boon will be "a wonderful character, a gunslinger," while the official character description noted that the character has a "quick draw" and had a romantic view of himself as a man out of a different time.

In addition to his role as Jay Kulina on DirecTV's Kingdom, Tucker has also appeared on Parenthood, and starred in the cult-favorite series The Black Donnellys.

Justified's final season kicks off on Tuesday, Jan. 20, on FX.
