Paris Saint-Germain's continental chances have been dealt a considerable blow with confirmation that Kylian Mbappe has been ruled out for around three weeks after suffering an ankle injury in the Coupe de France final.
"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," PSG's statement read.
Mbappe was the victim of a robust challenge from Saint-Etienne veteran Loic Perrin during Friday's cup final. The 21-year-old World Cup winner was spotted post-match on crutches with his right foot in a brace.
The Ligue 1 champions face Atalanta in a one-off quarterfinal match Aug. 12 in Lisbon as part of the revised Champions League mini-tournament.
Without Cavani and Mbappe in attack, Tuchel is likely to opt for a front-three that features Neymar, Mauro Icardi, and Angel Di Maria against Gian Piero Gasperini's high-scoring Champions League debutants Atalanta.
Mbappe's condition means the forward is certain to miss Friday's Coupe de la Ligue final versus Lyon.
