FX’s new boxing series didn’t deliver a knockout punch in the ratings Tuesday night, and instead took a few body blows from Nielsen (and the fighting puns will stop …. now).

Looks like only 1.5 million viewers (793,000 million adults 18-49) watched the series premiere, which not only is far cry from the mega opening of last year’s Justified (4.2 million), but also was on par with the now-deceased Terriers (1.6 million, though Lights out did edge out Terriers by 17% in the adult demo).
