Manchester City star Sergio Aguero reportedly suffered an injury scare while training with his Argentina teammates.
The 28-year-old is expected to miss his nation's World Cup qualifier against Paraguay, but it is unsure whether the striker will miss key fixtures for his club.
According to Marca, Aguero required treatment from Argentina's physiotherapists after hurting his calf muscle during a training session.
There has been no word from City as yet over the fitness of their star striker, who has scored 11 goals in all competitions so far this season.
The North-West outfit will face Everton and Barcelona in their upcoming fixtures.
