TAMPA, Fla. – The United Soccer League Wednesday announced a modification to the previously announced training moratorium that will allow Championship and League One clubs, at their option, to open outdoor fields for non-contact training in small groups as well as training rooms for player treatment starting on May 11.

The legaue said it was operating under the guidance of local and state health authorities.

The USL stated that small group settings will be limited to up to four players, with no more than one athletic trainer and one member of a club’s technical staff allowed on each field during a session.

Teams in areas where local and state recommendations for stay-at-home orders have not been lifted should not train or allow treatment that is prohibited by their jurisdiction.

Clubs must notify the league of their plans to return to the team’s training facility prior to re-opening and training is voluntary for players.

The USL previously extended its training moratorium through May 15 for all of its professional clubs.
