The games for Week 8 start early. The Detroit Lions and Kansas City Chiefs play in London starting at 9:30 Eastern, which is 7:30 AM Arizona time (Daylight Savings ended today). That game is on FOX.
After the Cardinals play the Browns on FOX, then there will be two afternoon games on in Arizona -- Cowboys/Seahawks on FOX and Jets/Raiders on CBS.
After those games are done, then the battle between the Packers and Broncos -- both unbeaten this season -- will be on Sunday Night Football.
