During the season, watch for injuries to your players. You may need to identify the player who replaces your team member on the field. New picks may not be made during the season unless certain circumstances arise. These circumstances are described on the
Rules Page
If you need to make a roster change becuase of injury or activate someone from your bench, then you must notify the League Commissioner ( me ). Injury substitutions must be made during the season within a reasonable amount of time.
Remember, the only stat which is counted is runs scored. Only the regular season counts. The playoffs do not count.
