Paris St-Germain forward Kylian Mbappe suffered a “serious right ankle sprain” in his side’s French Cup final victory over Saint-Etienne on Friday.
Mbappe, 21, left the pitch in tears after being fouled by Saint-Etienne defender Loic Perrin in the first half.
PSG say the injury will be re-evaluated in 72 hours by a doctor.
They face Lyon in the French League Cup final on 31 July and then Italian side Atalanta in the Champions League quarter-finals on 12 August. (BBC)
