THE Dons have today signed Swansea City defender Alan Tate until the end of the season.
The 31-year-old arrived at Pittodrie this morning and passed a medical.
Aberdeen FC were due to officially unveil the Englishman as their first January signing at a press conference this afternoon.
Tate is a former Swansea captain and has played in every defensive position.
Having started his career through the ranks at Manchester United, the Englishman has made over 300 appearances in 12 years for Swansea.
But he has been told by manager Michael Laudrup that he is free to leave the club in the summer.
His loan spell at Yeovil Town was cut short earlier this season when he picked up a hamstring injury.
Tate was a key member of the Swans side which propelled itself through the divisions and into the Premier League under Roberto Martinez and Brendan Rodgers.
However, his career was stalled in 2011 when he broke his leg in a golf buggy accident.
Dons boss Derek McInnes has brought in the defender as a replacement to outgoing loanee Michael Hector.
Hector is due to return to Reading on Sunday, following a successful loan spell at Pittodrie.
