The St. Louis Rams will take on the Detroit Lions on Sunday in the early FOX broadcast group per the map above via 506Sports (full hi-res photo here).
Here's the full early FOX group (gray denotes no early broadcast game on FOX):
Teal - Lions at Rams
The Rams swath most of Missouri with chunks of Illinois, Kentucky, Tennessee, Arkansas, Oklahoma and Kansas while the Lions grab nearly all of Michigan with pieces of Ohio and Wisconsin.
As both teams are 4-8 and washed out of any real interest for 2015 outside of their local fans, neither is going to command much interest on the broadcast market.
