Manchester City goalkeeper Claudio Bravo suffered a hip problem in Chile's 0-0 FIFA World Cup qualifier with Colombia on Thursday.
According to ESPN FC, Bravo was withdrawn from the game after 64 minutes having collided with Miguel Borja and then Santiago Arias in two separate incidents.
He told Fox Sports (h/t ESPN FC) he did not know what sort of time frame he could be out for, if at all: "At this time, it bothers me a lot. But we have to be smart and realise we have another match on Tuesday."
Bravo was a key summer signing for City boss Pep Guardiola.
