Goalkeeper Edouard Mendy has gotten back to Chelsea in the wake of harming his correct thigh while preparing with Senegal.
The 28-year-old joined the Blues on a five-year deal last month and kept a clean sheet on his Premier League debut against Crystal Palace.
Chelsea said Mendy “had a medical examination in a hospital in Rabat, where Senegal are due to play Morocco”.
The club added:
“Mendy has since returned to Chelsea where he will undergo further examinations.”
Senegal play Morocco in a friendly on Friday (19:00 BST kick-off).
