Brentford defender Shaleum Logan has joined Aberdeen on loan for the rest of the season.
The 26-year-old right-back, who is out of contract in the summer, could make his debut in Saturday's League Cup semi-final against St Johnstone.
Logan began his career at Manchester City, where he spent periods on loan at Grimsby, Scunthorpe, Stockport and Tranmere, and has made 85 appearances for Brentford since joining in 2011.
He told the Dons' website: "I first knew of Aberdeen's interest earlier in the week and I can't wait to get involved.
"There are so many big matches coming up and obviously I want to get playing as quickly as possible.
"The fans can expect a player who gives 110% in every game and I would describe myself as an attacking full-back."
