It is possible for teams to support each other with players, but it can only be done as follows:
U7 – U11 (Development Football)
A Player can play for any team in the same club at the age group except for festival or tournament events.
A Player is also allowed to play for his Club in an older age group but must be registered to that team, and therefore registered to both teams.
U12 – U18 (Competition Football)
It is a breach of League Rules for a Player to play for more than one Team in the same age group in the Competition in the same Playing Season without first being transferred.
A Player can be registered to play Saturday and Sunday as long as he/she is playing in a different league e.g. SYL & EEYL
