As you are aware the County FA maintains lists of suspended players. The onus is on clubs to regularly check to ensure that they do not play a suspended player.
The reason for this post is that I am aware that a number of players are facing suspension, from 15 December following the withdrawal of Countesthorpe Windows from the Leicester Sunday League.
When reviewing this list, included in
http://www.leicestershirefa.com/club/~/media/countysites/leicestershirefa/documents/discipline/sine-die-suspension-added.ashx
the League Registration Secretary recognises a number of the names and believes they are also registered with Alliance teams.
You may wish to check and certainly not play any suspended player. If that player also plays for an Alliance team, you may wish to encourage him to clear that debt with County FA to avoid any problems for Alliance teams.
