City have agreed a 93-day emergency loan deal for Middlesbrough defender Stephen McManus.
The deal sees the return of the 30-year-old centre-half who spent a brief loan spell at Ashton Gate between February and March.
With just one league appearance to his name for parent club Boro this campaign, McManus will relish the opportunity to play regular football and rejoin a number of familiar faces.
Manager Derek McInnes told bcfc.co.uk
: “Last season I felt he came in and gave us a real lift; hopefully he can do something similar this time around.
“Of course his loan spell was curtailed early last time and I think he feels he has unfinished business here.
“He was desperate to come back and now we have him for the next three months.
“Stephen is experienced at Championship level, has battling qualities, defends his box and can be the first-ball winner. He’ll be very dominant and a good professional to have about the place.
“This position is one we’ve been looking to strengthen for some time and it’s great we’ve got someone who can come in, is desperate to play and also knows all about us too.”
Lanark-born Stephen was a trainee at Celtic, making his professional debut under Martin O'Neill at Parkhead in season 2003/04.
He later established himself as a first choice centre-half during Gordon Strachan's all-conquering reign.
He won three Scottish Premier League titles, two Scottish Cup and two Scottish League Cup during his time at Parkhead, where he was a regular skipper.
McManus joined Boro on loan in season 2009/10, linking up with Strachan once more, before making the deal permanent for £1.5m in July 2010.
Internationally McManus has 26 caps for Scotland, with two goals, and has also taken the captain's armband on numerous occasions.
He is unable to face his parent club at the Riverside on November 24th, or play in the FA Cup third round. The deal - which runs until January 17th 2013 - is subject to Football League approval.
McManus has been handed squad number 19.
