La Liga has given Barcelona permission to sign a replacement for the injured Ousmane Dembele, according to Mundo Deportivo.
Demebele has to miss the Catalan giant's games due to his hamstring injury for six months, following the surgery in Finland.
Quique Setien's side now have 15 days to sign a player who is either currently playing in Spain's top division or is a free agent.
The new signing will only be able to play in La Liga matches, however, not being selected for the Champions League games.
Barcelona asked for permission to sign a replacement, sending the relevant documentation to La Liga's medical committee last Thursday.
They have been given the permission on Monday morning after the committee confirmed the injury as a long-term lay-off.
