Fabinho was removed from his country’s squad for the World Cup qualifiers against Venezuela and Uruguay next month and replaced by Everton’s midfielder Allan.
Liverpool are waiting to hear the duration of Fabinho’s absence – but will have to do without the Brazilian for at least the next three games.
Liverpool midfielder Fabinho has been scanned to determine the extent of his injury, which he sustained during the last Champions League match as Jürgen Klopp’s injury problems increased.
The head of the Reds, Jurgen Klopp, will report on Fabinho’s condition to the media on Friday.
The 27-year-old has undergone an investigation on the subject to determine the extent of the damage.
Fabinho was sent off with a suspected hamstring problem after Liverpool’s half-hour Champions League victory over Midtjylland FC on Tuesday.
He will also be absent from the Champions League duel in Atalanta next Tuesday, as well as the trip to League Cup winners Manchester City five days later.
But now it is clear that Liverpool will have to do without Fabinho at the earliest after the forthcoming international match break.
The Brazilian, who played as central defender with Virgil van Dijk and the injured Joel Matip, will miss West Ham United’s Premier League visit on Saturday.
Liverpool will resume after the international break with a performance in Leicester City on November 21.
19-year-old Rhys Williams (19), who is expected to play away at the weekend, is keen to make his Premier League debut alongside Joe Gomez as central defender.
