Dundee United have confirmed they have agreed a pre-contract with Aberdeen defender Mark Reynolds – with the former Motherwell star signing a three-year deal at Tannadice.

Reynolds has been on loan with the Arabs in January, making nine appearances, and will make his switch permanent in the summer, according to United’s official website.

The experienced defender has been named captain on each of his appearances and has made a big impression at Tannadice in his short time there.

With a top of the table clash against Ross County this weekend, it will be a big boost to Robbie Neilson’s side.

The former Scotland B cap leaves Aberdeen after making over 200 appearances since returning to Scottish football in 2012 after a stint with Sheffield Wednesday.

The 31-year-old should be a solid signing for the Arabs and, should they get promoted, his experience will be a massive help to United.

He was part of the League Cup winning side against Inverness in 2014 and was a consistent figure in Aberdeen securing four consecutive second-place finishes.

A serious knee injury against Cove Rangers in pre-season ruled him out of the start of the campaign but he was back in training before the end of 2018.

A loan deal to United sealed on deadline day to allow Reynolds to regain match fitness and has worked so well, Reynold’s has won a permanent switch out of it.
