Dundee United have completed a hat-trick of deadline day signings.
Centre-back Mark Connolly has joined from Crawley Town until 2021.
United will be the Irishman’s third Scottish club, having spent a season at St Johnstone and two at Kilmarnock.
The 27-year-old becomes Robbie Neilson’s ninth signing of a busy January window.
Neilson said: “Mark is a strong defender and a leader. He brings great experience and an excellent attitude to the dressing room and pitch. I am delighted to make him a Dundee United player.”
