Arena Football League:

The league's 2016 schedule, announced on the league's website on December 10, 2015, shows an eight-team league playing a 16-game regular season over 18 weeks, with two bye weeks for each team, one on a rotational basis and the other a "universal bye" for all teams during the Independence Day weekend, the first weekend in July. All teams will qualify for the postseason, meaning that the regular season will serve only to establish seeding.
