Dekel Keinan has joined Bristol City on loan until May following a lack of first-team opportunities at Cardiff City.
The Israel defender, 28, could make his debut in tomorrow's match against Championship promotion hopefuls Middlesbrough.
City boss Derek McInnes told the club website: "Dekel is another player who hasn't been playing recently.
"He feels he has something to prove and everyone I've spoken to has had positive words to say about him."
