The showrunner for the Netflix original series "Narcos" has left his post, causing the young show difficulty as it prepares for Season 2.

According to Deadline, the series originally placed Adam Fierro in the top spot for Season 2 of the show. As showrunner, he would have been responsible for how the show would progress moving forward, overseeing all aspects of the season's production, from storylines right down to the last details on the editing floor.

But now Fierro has departed the project and the upcoming season with no explanation.

This will be the second time a showrunner has departed the series since its debut late last summer. The original showrunner Chris Brancato left the series in order to start working an overall deal with ABC Studios. That was when the series picked up Fierro.

Although he has departed the series, Fierro had already completed his contractual obligations as far as writing and creative influence.

Taking his place will be Jose Padilha, who was originally scheduled to step back in Season 2, after serving as a director and executive producer for the show during the first season. Fellow executive producer Eric Newman will also be coming in to help with showrunning duties as well.

"Narcos" was a breakout hit with subscribers to the streaming platform and has been consistently ranked high in the website's vast collection of original and syndicate content.

Due to the immense popularity of the show, the series had been given the green light early on for a second season. It also earned a few award nominations at the Golden Globes, including nods for Best Drama Series and Best Actor (Wagner Moura).

Details of Season 2 are scarce at the moment, although fans of the show can simply do a bit of research into the history of Pablo Escobar if they want to know what to expect in the coming season.
