Spanish giants Real Madrid and Atletico Madrid have been banned from registering players for the next 18-months, ruling them out of the next two transfer windows, due to breaching rules over the transfer of under-18 players.
The ban begins next month, meaning they can still sign players this transfer window, and runs until July 2017.
Atletico was also fined AUD$1.28 million and Real was fined AUD$515,000.
"FIFA works hard to protect the rights of players under the age of 18 - whether male or female, amateur or professional," said FIFA in a statement.
"This is done through the enforcement of regulations prohibiting the international transfer of minors, or the first registration of minors in a country other than their own, except in specific circumstances."
