F/X is revving things up for another season of their newest drama. According to The Hollywood Reporter, the network has ordered a second season of their new series, Sons of Anarchy. 13 episodes have been ordered for the sophomore season and the main acting trio of Ron Perlman, Katey Segal and Charlie Hunnam are on board as well.

The show is performing consistently overall, even though the first-run airings of the episodes are receiving modest ratings. The series is averaging 3.5 million viewers per episode, but the fourth week saw a 1% increase from the premiere and the cumulative average audience is 5.4 million viewers, down just 3% from its premiere.

"We've never had a drama hold up so consistently in its first five weeks on the air," FX president/GM John Landgraf said. "It hasn't buckled in the face of broadcast competition, and it's fantastic from a quality standpoint."

Sons of Anarchy airs Wednesday nights at 10 PM on F/X.
