Jones has been tapped to play Zeke, the mysterious cousin of Rain Wilson's Dwight Schrute, THR said.
The potential spinoff, "The Farm," centers on Dwight as a beet farmer who also runs a bed and breakfast inn. Jones would join Thomas Middleditch, Dwight's brother Jeb; Majandra Delfino, Dwight's sister Frannie; and Blake Garrett as Cameron, his nephew.
Jones previously appeared on "Breaking Bad" as Badger, Jesse Pinkman's friend, "TRON: Uprising" and episodes of "NCIS."
Producers announced Tuesday the upcoming ninth season of "The Office" will be its last.
