From Variety.com: "CW's "Smallville" (1.7/4 in 18-49, 4.4 million viewers overall) and "Supernatural" (1.6/4 in 18-49, 3.9 million viewers overall) were both solid, though they figure to come down a bit since these preliminaries include averages for NFL football on the net's affiliate in New York."
From TVGuide.com: "Supernatural tacked on 710 thou to hit 3.91 mil. (But again, J-E-T-S.)"
