PARIS -- Kylian Mbappe will be absent for "approximately three weeks" due to an ankle injury which he picked up in the French Cup final last Friday, his club Paris Saint-Germain confirmed on Monday.

It means that the French international will undoubtedly miss PSG's League Cup final against Lyon this Friday, and the chance for him to appear in the Champions League quarterfinal against Atalanta on Aug 12 is also in doubt.

"The results of today's scan confirmed an ankle sprain with damage to the external ligament. The player is expected to be sidelined for approximately three weeks," a statement from the club said.

The 21-year-old limped off the pitch with an ankle injury after being brought down by Loic Perrin only half an hour into the match on Friday, in which PSG secured their second title of the season with a 1-0 win over Saint-Etienne. Brazilian star Neymar scored the only goal of the game.
