Manchester City defender Micah Richards is set for another month on the sidelines with an ankle injury.
Richards suffered the problem on Olympic duty and Blues manager Roberto Mancini expected him to recover in time for Sunday's Premier League match with Southampton.
However, the 24-year-old's recovery has not gone quite as well as planned.
"I think it will be three or four more weeks," said Mancini.
Mancini also confirmed Gareth Barry remains on the sidelines with an abdominal problem. However, Joe Hart could be fit after missing both the Community Shield and England's win over Italy with a back problem.
"Joe will train with the team tomorrow, then we will decide," said Mancini.
