Sheffield United have confirmed the signing of MK Dons defender George Baldock.
Baldock becomes Chris Wilder's fourth signing of the summer, after joining for an undisclosed fee. He has signed a three-year deal at Bramall Lane.
"George is another to fit the bill of the squad we are looking to build here at Bramall Lane," Wilder said.
"He is a great age and has great experience and will provide us with competition for places in an important part of the pitch. We've tracked him for a while, monitored his progress, and we're looking forward to working with him when we return to pre-season training later this month."
Baldock added: "I'm absolutely delighted to have signed and committed my future to this impressive club.
"I was excited when I heard of United's interest, for a number of reasons, including the manager's record over the past couple of seasons and the passion of the fans when they travelled to Milton Keynes a couple of months ago."
