Alisson has been ruled out of Liverpool’s Premier League match against Everton on Wednesday night.
The 32-year-old was forced off during Brazil’s 2-1 win against Colombia during the international break after clashing heads with Davinson Sanchez.
The Liverpool goalkeeper subsequently returned to the UK and missed Brazil’s 4-1 defeat to Argentina.
Brazil’s medical team revealed that Alisson had ‘minor complaints’ after the head collision and was substituted due to suspected concussion.
