Ladbrokes Championship leaders Dundee United have signed experienced defender Paul Quinn on a short-term deal until January.
The 32-year-old moves to Tannadice from Ross County and has also previously played for Motherwell, Cardiff City, Doncaster Rovers and Aberdeen.
Manager Ray McKinnon told the club website: "Paul gives us greater strength across the defensive line. He has been patient and showed a willingness to play for United by spending quite a few weeks in training with us."
