The USL, which at the professional level currently is comprised of the Championship and League One divisions, represents the second and third tiers of soccer in the United States, behind MLS. The USL also contains an additional tier, the semi-professional League Two.

The Athletic report indicated that the USL would ideally add a third league to its ecosystem in the coming years to make promotion and relegation more enticing and that it could begin as soon as 2024, if passed.

The vote is expected to take place at the USL board of governors meeting -- scheduled Aug. 9-11 in Colorado Springs, Colorado -- to gauge the interest of USL owners in incorporating promotion and relegation into the league.

Promotion and relegation is the model used by soccer leagues in nearly every country throughout the world, including England, Spain, Germany, Brazil and Argentina, but the idea has been kept at arm's length by MLS commissioner Don Garber.

The USL would be the first major sports league to employ promotion and relegation in the U.S., if approved.
