The United Soccer League is making moves to compete more directly with Major League Soccer, something the embattled Indy Eleven is using to bolster its case for remaining Indianapolis' sole professional soccer team.

The United Soccer Leagues (USL), representing American professional soccer's second and third tiers, voted to add promotion-relegation to their system. Currently, it is set up with the USL Championship featuring 24 teams and the third-tier USL League One featuring 14 teams.

United Soccer League (USL) club owners voted on Wednesday for a promotion and relegation system, marking the first time the European-style system would be implemented in the United States.
