Oswalt, whose television credits include The King of Queens and The United States of Tara, has been enlisted for a recurring role as Bob Sweeney, reports TVLine.
Oswalt's character is a constable who is a high school classmate of Raylan Givens (Timothy Olyphant). He has been brought in by Raylan to watch his father's house.
Earlier this year, the drama's creator Graham Yost revealed that he would like to cast Oswalt as he is a fan but that his schedule made him unavailable.
