Barcelona will not be permitted to make any signings until 2016 after their appeal against a two-window transfer ban was rejected by the Court of Arbitration for Sport (CAS).
The Catalans were initially banned by FIFA after being found guilty of signing underage players from outside of Spain.
CAS returned its verdict this morning and said they found no grounds to overturn FIFA's decision.
"CAS has dismissed the appeal filed by FC Barcelona against Fifa regarding the decision issued by the Fifa Appeals Committee on August 19, 2014," said a CAS statement.
"The panel found in particular that FC Barcelona had breached the rules regarding the protection of minors and the registration of minors attending football academies...”
“Accordingly, the Fifa decision is confirmed in full and the sanction remains in force."
Barcelona appealed the original decision, with the delay allowing them to sign the likes of Luis Suarez and Ivan Rakitic this summer.
