Brazil goalkeeper Alisson, who was forced off the field after a clash of heads during Thursday's 2-1 win over Colombia in a World Cup qualifier, has left the national team and will return to his club Liverpool, the Premier League side said on Friday.
Alisson and Colombia defender Davinson Sanchez both collapsed after clashing heads during the second half. Medical staff rushed onto the pitch to treat them, before both players were substituted.
Media reports said Alisson, 32, was taken off as a precaution after feeling dizzy following the injury.
"Alisson is travelling back to Merseyside and will undergo assessment from the Reds' medical staff," Liverpool said in a statement.
Alisson later played down fears of a serious injury.
"Hey guys, just to let you know I'm fine! Just have to follow the protocols! Thanks for the messages," he posted on his Instagram story.
Brazil are second in the table in the CONMEBOL World Cup qualifiers, with the top six set to directly qualify for the next year's finals.
Liverpool, who have a 12-point lead at the top of the Premier League standings, host Everton on April 2.
