The Argentine striker hobbled off at Anfield a minute after Andy Carroll had opened the scoring for the home side as fears mount that he could now be out of Saturday's Wembley tie
Tevez was substituted in the 15th minute of their Premier League clash against Liverpool with a suspected hamstring injury, and speaking to reporters after the game Mancini confirmed his captain may struggle to be fit for the clash at Wembley.
"Carlos has a hamstring problem," he said.
"I think it will be very difficult for Saturday – we think he will need another two weeks.
"I think it will be very difficult for him to play in the semi-final."
A minute after Andy Carroll had put Liverpool ahead with his first goal for the club Tevez looked in pain as he limped in the centre circle at Anfield.
The Argentine proceded to pass the captain’s armband to Vincent Kompany and signalled to Roberto Mancini to be substituted. However the Blues boss refused to rule out the striker for the remainder of the season saying; "No, no, no. I don't think so."
Mancini, and all City fans, will be hoping that their star man's withdrawal is just a precaution with the crunch game against United at Wembley coming up this weekend.
