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."
Keinan tweeted last night: "I'm really looking forward to the first training session tomorrow."
