Neymar left the field in tears after rolling his ankle in the 60th minute during the Coupe de France win over Strasbourg, just three weeks before PSG face Manchester United in the Champions League
Paris St-Germain manager Thomas Tuchel says Neymar is “worried” after he injured his ankle as they travel to Old Trafford for the first leg of their Champions League last-16 tie on 12 February.
“Ney is worried, because it is the same foot, the same place,” said Tuchel.
The former Barcelona forward, who has scored 20 goals in all competitions so far this season for the Ligue 1 leaders, injured the same ankle last February and missed the rest of the season, only returning to fitness in time to play for Brazil at the World Cup.
“He is at the hospital and I must wait for the doctor to give me news.”
PSG midfielder Marco Verratti is already doubtful for the tie with Manchester United after suffering an ankle injury during the 9-0 win over Guingamp on Saturday.
Goals from Edinson Cavani and Angel di Maria sealed the win over Strasbourg.
