UPDATED: FX has decided not to renew freshman boxing drama Lights Out for a second season. Lights Out was one of the most critically praised new series this season, punctuated by a breakout performance by Holt McCallany as the title character, a washed-out former heavyweight champion looking for a comeback. But, just like with FX’s now-defunct drama Terriers last fall, Lights Out never found traction in the ratings, leading to FX’s decision to cancel it after one season. It premiered in January with 1.5 million viewers and slipped further throughout its run, averaging 863,000 viewers per first-run episode vs. 2.7 million for Justified.

FX president John Landgraf praised the quality of the show and McCallany’s performance and said that in the end, it all came down to Lights Out’s subject matter “The audience didn’t want to watch a show about boxing,” he said. “We never got any traction” during the pre- and post-launch marketing and publicity campaign.  Landgraf said that he is not concerned by having two new series in row, Terriers and Lights Out strike out. “That’s baseball,” he said. “If you put on 4 shows, two of them work, Sons of Anarchy and Justified, and the other two are Terriers and Lights Out, that’s pretty good.”
