Lionel Messi has injured his left hamstring after FC Barcelona's 1–0 victory over Athletico Bilbao, the club announced.
“[Messi's] presence in his country's World Cup qualifying matches will depend on how the injury develops,” Barcelona said in a statement.
Messi is on his way to Argentina to join the national team as they prepare to host a World Cup qualifying match against Uruguay on September 2 and then travel to Venezuela for a game on Sept. 7.
Argentina's national team already suffered a blow as Sergio Aguero withdrew from the team due to an injury in Manchester United's game against West Ham United.
