You mean that wasn't filler in the first place? :covri:
NO-Carolina is shaping up like SF-Seattle, the game Fox protected. (The other protected game is Cinci-Indy.)
Refresher: Weeks 11-16, games may be flexed out. CBS & Fox may protect one game per week 5 out of those 6 weeks. (Both left week 12 unprotected since NBC already has Denver-New England.) Schedule changes are made 12 days in advance, as noted above. For week 17, no games are protected and the schedule can change 6 days before the game (i.e. right after week 16).
