Manchester City goalkeeper Claudio Bravo could miss the remaining five games of the season after sustaining an injury in Thursday's 0-0 Premier League draw with rivals Manchester United.
Chilean Bravo was carried off on a stretcher in the 79th minute and replaced by Willy Caballero.
"Of course he has an injury, probably [out] for some weeks," manager Pep Guardiola said after the game. "I don't know if he will be available again this season."
Fourth-placed City, a point and a place above United, travel to relegation-threatened Middlesbrough on Sunday.
