BUENOS AIRES, Argentina (AP) Sergio Aguero will miss Argentina's World Cup qualifier against Paraguay next week with a left-leg injury.
The Manchester City striker left the field in the first half of Thursday's 2-0 defeat to Ecuador.
''The studies we did today show that Sergio Aguero has a grade-two muscle tear,'' the Argentine Football Association said in a statement Friday.
The statement did how say how long Aguero would be sidelined.
But the injury will be a worry for both City and Argentina, which hosts Brazil in Buenos Aires on Nov. 13 in a key qualifier.
Aguero is Argentina's fourth highest all-time scorer and his absence comes at a bad time for his country, with Lionel Messi expected to be sidelined until late November with an injured left knee.
