Paris St-Germain forward Neymar will be out for up to eight weeks after suffering ankle ligament damage, the French club have confirmed.
The 29-year-old Brazil international was carried off on a stretcher in the last few minutes of Sunday's 3-1 away victory at Saint-Etienne.
Neymar is set to miss seven PSG Ligue 1 matches and a Champions League tie.
"The examinations carried out confirm Neymar suffered a sprained left ankle with ligament damage," said PSG.
The club added that a further update would be made in 72 hours.
Domestically, PSG are 12 points clear of second-placed Rennes, while in the Champions League they are guaranteed to finish second in Group A and advance to the last 16.
PSG play Club Bruges at home on 7 December, before the tournament resumes in February.
