Jökull Andrésson's emergency loan from Reading has been extended for another seven days.
The extension means that Jökull will be available for City's matches against Colchester United and Gillingham in the Emirates FA Cup.
Jökull has started all of City's last seven matches in all competitions, keeping two clean sheets.
In line with EFL rules, we are able to sign Jökull on seven day periods at a time whilst both Lewis Ward and Jonny Maxted are out with injury.
