And the Official NFL Schedule:
NFL.com Schedules Page presently also shows this schedule change, but no SNF game at the present, does this possibly mean that NBC is trying to get the Lions and Saints game scheduled for 1pm to be that Sunday Night game? It would be kinda neat if it does happen, but just thought I'd post what I saw.
