The Blades are delighted to announce that both Jamie Murphy and Terry Kennedy have extended their contracts.
The duo have committed their immediate future to the Club by signing the paperwork that will keep Murphy at S2 until the summer of 2017 and Kennedy until the end of the 2015-16 campaign. There's also an option to extend both by a further year.
Murphy, 25, has impressed since settling in following his move to Bramall Lane in January 2013. He has scored 13 times in 82 starts for the Club, including a goal at Wembley in last season's FA Cup semi-final.
Homegrown Yorkshireman Kennedy, 20, has battled with injury problems but has made 12 senior appearances for the Club. He was part of the Blades team that reached the final of the FA Youth Cup and earlier this month helped keep a clean sheet in the FA Cup success at Queens Park Rangers.
"Both are influential members of the squad and have the potential to be even better," said boss Nigel Clough. "Jamie has caused Premiership defenders countless problems in our cup runs, whilst Terry is a no-nonsense defender, the type of which are particularly appreciated at Bramall Lane."
Managing Director Mal Brannigan added: "To have secured the services of both Jamie and Terry during this transfer window indicates further the intent that this Club and its owners have of building a bright and stable future. This is on the back of adding four players to the squad in the last eight days and underlines the owners' commitment to protecting the playing resources already at the Club."
Meanwhile, Diego De Girolamo has decided to decline his contract offer.
