City manager Roberto Mancini revealed the full extent of Boateng's injury on Friday, which was sustained while on international duty with the Germany team last week.
Mancini said: "He will have surgery in the next two or three days. Maybe he will be fit for the last two games."
There was more positive news coming out of Eastlands regarding Micah Richards.
Mancini said he was hoping that the defender, who suffered a hamstring injury last week while with the England Under-21 team, will be fit in time for the semi-final clash with rivals Manchester United at Wembley on April 16.
"We are trying to get him fit for the semi-final. I don't know if it is possible but we hope," said Mancini.
