Donal Logue will appear in the final three episodes of this currently airing season of Sons of Anarchy, which concludes on December 4th. He will play a skilled U.S. Marshal named Lee Toric, forced into retirement due to his violent nature. (U.S. Marshal? FX? Do we smell a potential Justified cross-over brewing here?}
Donal Logue himself announced the news, saying this.
"Lucky 2B part of amazing finish on this season's Sons of Anarchy [Kurt Sutter] pushing TV boundaries-shockingly awesome stuff coming down pike!"
