  • Prior to the first game of the season, teams must have 7 players confirmed on the roster in MyESSC. This number is equal to the total number of players required on the field in the above chart.
    • If the minimum amount of confirmed roster players is not met, the team will receive a loss for every game played until the requirement is met.
    • Minimum female requirements are inclusive of anyone who identifies as female (i.e. players who identify as M or X do not count towards F minimums).
  • Prior to the first playoff game, teams must have all players who are playing in the playoff game(s) displayed as part of the confirmed roster in MyESSC.
