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. With Thursday Night Football pushing the Rams into national coverage, this is the last home game for the Rams amid the early bracket.
