FIFA has confirmed that Al-Nassr is currently banned from registering new players.
The world football governing body also noted that the ban will be lifted if the Saudi Arabia Pro League club settles the debt they owe Leicester City.
Al-Nassr has failed to pay the Premier League club money they owe for Ahmed Musa’s transfer.
Musa signed for the Knights of Naja in a €16.5 million deal in 2018, shortly after impressing at the World Cup in Russia.
While Al-Nassr has paid the transfer fee, they are yet to pay the Foxes €460,000 in performance-related add-ons.
A FIFA spokesman said: “Al-Nassr is currently prevented from registering new players due to outstanding debts.
“Relevant bans will be lifted immediately upon the settlement of the debts being confirmed by the creditors concerned.”
