A “Sons of Anarchy” spinoff is in the works at FX with Kurt Sutter at the helm, Variety has confirmed.

Sutter — whose “Bastard Executioner” bows Sept. 15 on the cable net — has long hinted at a “SOA” spinoff, which is now officially a possibility with a new development deal just secured for the offshoot.

Few details are known, as the series is in very early development, but the spinoff would focus on the Mayans motorcycle crew and would be set in the Northern California motorcycle club scene.

In the flagship series, the Mayans, the Oakland-based Hispanic gang, ran heroin factories and were involved in prostitution.

Sutter would serve as exec producer on the untitled project, though he is searching for a showrunner to run the day-to-day grind, as he will remain focused on “Bastard,” among other upcoming projects. Fox 21 Television Studios and FX Productions would produce the offshoot.

Sutter’s “Sons of Anarchy” is FX’s most popular series to date. The gritty drama ended its seven-year run last December with 6.4 million viewers in same-night viewing and 9.3 million in Live+3, according to Nielsen. Overall, its seventh and final season goes down as the highest-rated in FX history, averaging 7.55 million viewers and about 5 million in the adults 18-49 demo.
