Greg Cunningham will see out the season at Nottingham Forest, with Manchester City agreeing to extend his loan agreement.
The Republic of Ireland international initially linked up with the Reds in October, with that deal set to run until the turn of the year.
He would have been able to figure in a meeting with Cardiff on New Year's Eve, but would then have been expected to head back to the Etihad Stadium.
Cunningham is, however, still some way down the pecking order and City and has been able to get useful game time under his belt with Forest.
He will now spend the remainder of the 2011/12 campaign at the City Ground, with Reds boss Steve Cotterill delighted to have retained the services of a key defensive figure.
"I think he's done really well and has caught everyone's eye," he told the club's official website.
"I think our supporters like him, which is obviously important, and we're really pleased he's staying with us.
"Greg is a good lad. He comes in every day, does his bits and pieces after training in the gym and we've been delighted with him.
"He's a really good footballer and a fantastic lad - he has fitted in around the place very well.
"Everything has now been agreed with Manchester City and we're just finalising all the paperwork that needs to be done."
