United's new promotion campaign for next season has been given a double boost with the Club taking up the contract extension options of Paddy Kenny and Nick Montgomery.
The Republic of Ireland International goalkeeper kept an impressive string of clean sheets last season whilst Montgomery improved his reputation amongst the Blades faithful with some stirring displays during the run-in.
In addition, new contract offers will be made to senior professionals Ian Bennett and Leigh Bromby who have been solid and dependable members of the squad which all but reached the Premiership.
Young prospects Sam Wedgbury and Matt Lowton will be offered new deals and are set to continue their development in Hungary with newly promoted Ferencvaros until January, alongside fellow United Academy products Jordan Robertson and Liban Abdi.
Meanwhile, Adam Chapman, who spent half of last season out on loan, was under contract but will join Oxford United for a £15,000 fee, dependent on games played, plus a 50% sell-on clause in any future transfer.
Danny Webber and Ugo Ehiogu will leave Bramall Lane as their contracts have expired and the Club would like to thank them for their efforts.
The achilles injury sustained by Ehiogu sidelined him from just before Christmas which was a huge loss, whilst Webber's contributions have also been hampered by injury during his time at the Lane.
Keith Quinn, Jamie Annerson, Maxime Chanot and Ben Starosta have also been released, whilst Craig Beattie, Greg Halford, Arturo Lupoli and John-Joe O'Toole, who all ended the season on loan with United, will return to their respective clubs after making good contributions.
Kevin Blackwell will need to reshape his squad for the new challenge and will test the market by making Lee Hendrie, David Carney, Nicky Law and Zeyn S-Latef available for transfer.
In terms of the Blades promotion push this will provide all four with the opportunity of first-team football elsewhere whilst reducing the wage bill and enabling more flexibility for new signings.
