A friend of FX will join the already impressive roster of guest stars on Sons of Anarchy this season.

Donal Logue — who last appeared in the network’s series Terriers — will play a brilliant and dangerous U.S. Marshal named Lee Toric who is forced into retirement because of his history of violence. He’ll appear in the drama’s final three episodes before it wraps its current season on Dec. 4.

“Lucky 2B part of amazing finish on this seasons’s Sons of Anarchy [Creator Kurt Sutter] pushing TV boundaries-shockingly awesome stuff coming down pike,” Logue recently tweeted.

Here’s an exclusive first look of Logue as Toric:
