PSG star Kylian Mbappe is out of their Champions League quarterfinal against Atalanta.

The World Cup winner had scans on his ankle injury on Monday and PSG have announced he will miss the next three weeks.

Mbappé will not be available for Friday's last ever Coupe de la Ligue final against Lyon and will not have enough time to make the Atalanta clash.

The last-eight Champions League clash in Lisbon will be played on August 12, although Mbappe could yet be fit for the semi-finals if PSG advance.

"The results of today's scan confirmed an ankle sprain with damage to the external ligament," PSG's statement read.

"The player is expected to be sidelined for approximately three weeks."
