Spartans have 2 teams one in the East of Scotland League the other play in the Juniors. If a player plays in the EOS league one week and they choose to play him in the Junior league the following week, I believe they have to 'free' him from his Scottish league registration, then reinstate him to Junior and vice-versa.
Oh and they may have to pay a registration fee to the appropriate governing body after every 'transfer'.
Scottish fitbaw eh...
