The Lions also play in the National Premier Soccer League (NPSL), a national outdoor league at the fourth tier of the American Soccer Pyramid.

The Lions formed a men's adult team in 2006 and entered play in the PASL 2006–07 Winter season.

The team went hiatus for the 2008–09 season and returned to play both leagues in 2009.

After their second NPSL campaign the team played exclusively indoor soccer for five seasons.

In early December 2014 the team announced it would return to the NPSL for the 2015 season.
