In order to be included in player stats emails you need to input your data into Full-time/Matchday App by midnight 3 full days after a match. So if your game is on a Saturday, your stats should be submitted by midnight on Tuesday. This also applies to midweek games (e.g. results for Tuesday games need to be submitted by midnight on Friday for the email on Saturday).
What if the deadline is missed?
Players will not receive an email for that fixture. However all stats submitted with the FA Full-Time system will still be recorded and feature within your team and personal stats in your next email.
