Chelsea goalkeeper, Edouard Mendy has picked up a thigh injury during a Senegal training while on international duty with his country.
The goalkeeper has immediately returned to London for assessment by Chelsea’s medical team.
Blues boss Frank Lampard will hope Mendy can recover in time to face Southampton at Stamford Bridge in his team’s next Premier League game on October 17.
Mendy joined Chelsea from Rennes in a £22 million ($28 million) deal last month.
The 28-year-old kept his first clean sheet for the club in his first Premier League start against Crystal Palace last Saturday.
“The Senegalese Football Federation has announced the withdrawal from their squad of Edouard Mendy due to injury,” a Chelsea statement said on Friday.
“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.”
If Mendy is sidelined by his thigh problem, Lampard will have to turn to Kepa or Willy Caballero.
