Sons of Anarchy has tapped Harold Perrineau to join the Season 5 cast in the critical role of Damon Pope.

The Lost vet will play the ex-drug kingpin whose daughter was murdered by Tig in the Season 4 finale, creating what series creator Kurt Sutter recently called a “clusterf***” for Jax and SAMCRO.

“I definitely wanted to lay some track for Season 5 and put some complications already on Jax’s shoulder as he’s sitting at the head of the table,” Sutter told TVLine last year. “He’s already got a problem [going into Season 5].”

This marks SOA‘s second major Season 5 hire. Last month, Jimmy Smits was cast in a major season-long arc as Neron “Nero” Padilla, a Latino gangster who becomes an unlikely (and dangerous) mentor for Jax.
