The striker who has 13 goals and 11 assists this season in Ligue 1, has not played since a 4-3 win over Lille last month, and has missed PSG’s last two games.
“Neymar Jr has had several episodes of instability in his right ankle in recent years,” PSG said in a statement.
“Following his last sprain contracted on February 20, the medical staff… recommended a ligament repair operation to avoid a major risk of recurrence. All the experts consulted have confirmed this necessity”.
“A delay of three to four months is expected before his return to training.”
The club’s coach, Christophe Galtier stated that Neymar’s absence would be a significant loss.
“He is one of the top scorers and assist providers in Ligue 1, so he is a big loss,” Galtier told reporters.
“Without Neymar, we may have two midfielders and three attackers or three midfielders and two attackers. There are players who can get in behind from all sorts of different positions.”
PSG are top of the league with eight points over second-placed Olympique de Marseille. They face Bayern Munich in the Champions League last-16 second leg on Wednesday after losing the first leg 1 – 0.
