Manchester City defender Micah Richards feels a hamstring injury may rule him out of the FA Cup semi-final clash with rivals Manchester United.
Richards was stretchered off three minutes into England Under-21s 4-0 victory over Denmark on Thursday night, and head coach Stuart Pearce revealed the full-back fears the worst.
"He's got a hamstring problem and he's diagnosed himself as being out for four weeks - that's Dr Richards for you," said Pearce.
That would rule him out of Sunderland and @Liverpool and open the right-back spot for Jerome Boateng. Unless Zabaleta were to return from compassionate leave sooner than expected.
