Bristol City have completed the signing of Fulham defender Matthew Briggs on a one-month loan deal.
The 21-year-old can perform in a number of positions including centre-back, left-back and the left side of midfield.
But the youngster is expected to challenge at full-back after Derek McInnes has been forced to use a number of players in that area following long-term injuries to Greg Cunningham and Wolves loanee George Elokobi.
"It's common knowledge that injuries have left us short in defence over the past few weeks and we're delighted to get Matthew on board," McInnes said.
"He'll certainly offer us cover at left-back while Greg (Cunningham) gets himself back to full fitness. Greg is making good progress but he's nowhere near yet.
"We know all about Matthew because we came close to signing him last season. He's a very highly-rated defender who can play in a number of positions and this loan move works for all parties concerned."
