The United States Soccer Federation Division-2 Professional League is the second division professional soccer league in the United States. In 2010, the United States Soccer Federation formed an agreement between United Soccer Leagues (USL) and the North American Soccer League (NASL), under which the USSF would operate the league in the 2010 season and work alongside the USL and NASL on day-to-day activities.
The league consists of two conferences of six teams named the USL Conference and the NASL Conference. The USL Conference includes the Austin Aztex, Minnesota Thunder, Portland Timbers, Puerto Rico Islanders, Rochester Rhinos and Tampa Bay Rowdies. The NASL Conference is made up of Crystal Palace Baltimore, Carolina RailHawks, Miami FC, Montreal Impact, AC St. Louis and Vancouver Whitecaps.
Each of the 12 teams will play 30 regular season games for a total of 180 games. The season will run from the second week of April until early October, with the playoffs to be contested during the following weeks.
