Aberdeen have signed former Dunfermline Athletic and Dundee United defender Callum Morris on a one-year contract.
The 26-year-old, who was with Newcastle United as a youngster, makes the switch to Pittodrie after spending the last two seasons at Tannadice.
He told the Aberdeen website: "I got a call from my agent to say the manager had been in touch and as soon as I heard that I had my mind set on coming up here."
