His injury is a blow for manager Pep Guardiola, who got rid of two City goalkeepers in the close season. But it is a short-term solution to his issues, and the 29-year old Dutchman will have to return to the Camp Nou eventually.
While Grimshaw is yet to make a single senior appearance, he signed a three-year contract at the club in June.
Bravo himself has attempted to put on a courageous face over the matter.
Midfielder Kevin de Bruyne has already been ruled out for three months after picking up a knee injury in training. This leaves City with the inexperienced Daniel Grimshaw as the sole second-choice goalie in the first-team squad.
The player tweeted: "No matter what happens, or how bad it looks today, life will go on, and tomorrow will certainly be better".

Adrian Peterson to meet with the Redskins on Monday
That necessitated signing Peterson and Smith, though coach Jay Gruden gave Kelley a vote of confidence on Sunday. Running backs Jamaal Charles , 31, and Orleans Darkwa , 26, also visited with Washington over the weekend.
After City sold goalkeepers Joe Hart and Angus Gunn in the close season, Guardiola only has 21-year-old academy product Daniel Grimshaw as back-up to Brazilian global Ederson.
Bravo ousted Hart when he joined City from Barcelona in 2016 but lost his place to Ederson after an indifferent first season.
On Monday night, the Premier League champions revealed that scans on Bravo "confirmed a rupture in the tendon of his left foot".
The Chilean will fly to Barcelona for further tests later in the week.
