The upcoming series, if picked up by FX, follows the story of EZ Reyes, played by JD Pardo, who is a prospect in the Mayan MC charter in the Mexico/California border. Irby will play Obispo "Bishop" Losa, who is from the Mayan MC's Santo Padre Charter. He hails from the Salton Sea, where he comes from a broken family. He was later raised by his cousin, Marcus Alvarez's (Emilio Rivera) family. Alvarez is the founder of the the Mayan MC. Bishop's background also include a stint in Iraq and Pelican Bay, and he is described as someone who is "deadly" and "loyal."

Production undergoing reshoots

Back in July, Variety reported that the pilot for FX's "Sons of Anarchy" spinoff "Mayans MC" will be completely reshot.

The project has been completely revamped, with Norberto Barba coming in to serve as executive producer and director. Creator Kurt Sutter, who was originally set to direct and produce, retreated to the writers' chair instead. In July, it was reported that JD Pardo will play EZ Reyes, while Edward James Olmos, Richard Cabral, John Ortiz, Antonio Jaramillo and Clayton Cardenas were all set to star in the pilot as well.

"Mayans MC" isn't the only production to undergo reshoots, as "Sons of Anarchy" also had some reshoots back in 2008. Ron Perlman replaced Scott Glenn as Clay Morrow in the pilot, causing them to reshoot all of Glenn's scenes. "Sons of Anarchy" originally ran on FX from 2008 to 2014, and starred Charlie Hunnam as Jackson "Jax" Teller.
