Dundee have signed former Tottenham and Liverpool centre-back, Steven Caulker.
The 26-year-old, who has one England cap, was a free agent after being released by QPR a couple of months ago.
Caulker has agreed an 18-month deal.
He has had a bit of a nomadic career, spending time at Swansea City, Cardiff City, QPR, Southampton and Liverpool.
Neil McCann has now signed two centre-backs in less than a week, with Angolan international Genseric Kusunga agreeing terms last Friday.
Despite the fact that Jack Hendry has left for Celtic, McCann now has several options in that position.
