Prior to Tuesday's announcement, the league announced where each international game would take place. Three will occur in London, where the NFL began playing games in 2007. The league will also see a return to Brazil, where the Philadelphia Eagles and Green Bay Packers opened their season last year.

There are Friday games in Week 1 and on the day after Thanksgiving. There are three Christmas games on a Thursday. There are late-season Saturday games. An 18-game regular season could be coming within the next few years. For now, it remains a 17-game season over 18 weeks.
