Liverpool midfielder Thiago Alcantara is expected to be out for several weeks with a hamstring injury suffered in Saturday's Premier League opener.
He will have a second scan later this week, although Liverpool do not consider the injury to be serious.
They are already without midfielders Curtis Jones and Alex Oxlade-Chamberlain.
Liverpool play Crystal Palace, Manchester United, Bournemouth and Newcastle in August before visiting Everton on 3 September.
