Liverpool midfielder Naby Keita will have a scan when he returns to the club after being injured playing for Guinea.
Keita hurt his hamstring in Tuesday's 1-1 draw in Rwanda in an Africa Cup of Nations qualifier, reports Agence France Presse.
The 23-year-old has made 10 starts for the Reds since joining from RB Leipzig.
Keita is the fourth Reds player - along with Mohamed Salah, Sadio Mane and Virgil van Dijk - to be injured in the international break.
