Aberdeen have announced the signing of defender Tommie Hoban on a season-long loan from Watford, who have the option to recall in January.
The 24-year-old made his debut for the Hornets in 2011 at the age of 16, and has gone on to make 54 appearances for the club.
"Tommie is a player we had last week and thankfully we managed to get the deal resurrected," Aberdeen manager Derek McInnes told the club's official website.
"First and foremost he's an excellent defender and it's well known that we've been in the market for another defender and to get a player of his quality from Watford is a great piece of business.
"Although he can play anywhere in the defence, centre-back is his preferred position."
The Englishman could make his first appearance for the club in their Europa League tie with Burnley tomorrow night.
