Aberdeen have completed the permanent signing of defender Mark Reynolds on a four-year deal, after he was released by Sheffield Wednesday.
The Scotland B Cap has been on loan at Aberdeen for the last year, having joined last January, and extended his deal in the summer.
Sheffield Wednesday cancelled the contract of the defender on deadline day, and Aberdeen moved quickly to secure the defender on a contract that will keep him at Pittodrie until the summer of 2017.
Speaking to the official Aberdeen website, he said: "After a spell of uncertainty, it's great to get my future sorted out and know that I'm going to be in the north-east for the foreseeable future.
"My family settled in Aberdeen very quickly and we really like the area and with the recent birth of our son Lucas, it's a huge boost to know that we'll be staying here.
"It's up to me to repay the faith the club has shown in me and I do believe we have a squad capable of bringing success to Aberdeen.
Reynolds has gone on to make 39 SPL appearances, and has been a virtual ever-present in Craig Brown's side.
The defender moved from Motherwell to Sheffield Wednesday under Alan Irvine in January 2011, but managed only 14 starts, falling out of favour when Irvine was replaced by Gary Megson only a month after Reynolds arrived.
