New Chelsea goalkeeper Edouard Mendy, on international duty with Senegal, suffered a thigh injury.
Last month, the 28-year-old completed a move from Rennes to Stamford Bridge and claimed a clean sheet last Saturday during his first Premier League start against Crystal Palace.
Mendy is back in London and will be tested by Chelsea, who will be next in action at Southampton ‘s home on October 17.
Kepa Arrizabalaga, who cost the Blues £72million when he joined Athletic Bilbao in 2018, expressed his optimism earlier this week that he could take back West London’s number one spot.
On Wednesday, the Spaniard kept a clean sheet against Portugal and when Southampton visit, Chelsea boss Frank Lampard may have a selection headache.
“The Senegalese Football Federation has announced the withdrawal from their squad of Edouard Mendy due to injury,” a Chelsea statement read.
“The goalkeeper sustained an injury to his right thigh during training on Wednesday and had a medical examination in a hospital in Rabat, where Senegal are due to play Morocco tonight.
“Mendy has since returned to Chelsea where he will undergo further examinations.”
