For the second straight week, the NFL on CBS sank double-digits from last year.

The Week 2 NFL singleheader window delivered an 8.4 rating and 14.5 million viewers on CBS Sunday, down 24% in ratings and viewership from last year on FOX (11.0, 19.2M) and down 14% and 13% respectively from 2015 on CBS (9.8, 16.7M).

The 8.4 rating is the lowest for the Week 2 singleheader since at least 1998. The first two NFL windows on CBS this season have both declined double-digits to multi-year lows.

Sunday’s telecast featured Patriots-Saints, called by CBS rookie lead analyst Tony Romo, in 41% of markets — including Dallas-Ft. Worth, where he played his entire career.
