A Spanish magistrate, leading an investigation into alleged irregularities in Neymar's move to Barcelona in 2013, said the Brazilian superstar could face up to six years in prison.
A Spanish judge says fraud and corruption charges brought against Neymar could merit a prison sentence of up to six years when the Brazilian forward stands trial.
Prosecutors were seeking a two-year sentence for the Paris Saint-Germain player for alleged irregularities related to his transfer to Barcelona five years ago, but the court said on Wednesday a sentence of four to six years could be handed down if Neymar is found guilty.
The decision is a setback for Neymar because in Spain sentences of two years or less for first offences are usually suspended, meaning he would avoid any jail time.
The charges were brought after a Brazilian investment group said it received a smaller compensation because part of Neymar's transfer fee was concealed by those involved.
Neymar's parents, Barcelona president Josep Bartomeu, and former president Sandro Rosell also faced charges, along with Barcelona and Brazilian club Santos.
They all denied any wrongdoing.
The trial's date has not been set.
