Old Guard Shield matches are determined by the USL regular season schedule. Each home and home series between the “participating” teams will count towards the standings. A total of 2 games per team and 2 games overall will be tracked in 2023. If teams host each other more than once due to USL scheduling the last home game will count towards the standings. U.S. Open Cup and USL Playoff matches do not count towards the Old Guard Shield.
