Barcelona striker Sergio Aguero has been ruled out of action for 10 weeks because of a right calf injury, say the La Liga club.
In a statement, Barca say tests on the Argentine forward have confirmed a tendon injury and would be out for around 10 weeks, meaning he will not make his debut until October 17 at the earliest, when they host Valencia in La Liga.
Aguero, 33, joined Barcelona from Manchester City on a two-year contract in June.
He spent 10 years at City, during which time he became the club’s all-time leading goalscorer with 260 goals in 390 games.
Aguero won the Copa America this year with Argentina, alongside Lionel Messi, who has confirmed his departure from Barca.
Barcelona coach Ronald Koeman is now short of striking options for his team’s opening league game against Real Sociedad on Sunday, with Martin Braithwaite, Antoine Griezmann and Memphis Depay his only available forwards.
Messi is reportedly finalising a move to Paris St Germain a day after his teary farewell from Barca, who could not afford to sign him to a new contract.
