Richard Cresswell has left the club by mutual consent to enable him to join York City on a free transfer.
Cresswell joined the Blades, initially on-loan from Stoke City in September 2009, before making the switch a permanent one in January 2010. In his 37 appearances that season, the striker scored 14 goals, to finish United's top scorer in the 2009/10 campaign.
The 35-year-old marksman, who, in total scored 30 goals in 141 appearances for the Blades, leaves Bramall Lane with a glowing reference from new boss David Weir:
"Richard has been a great servant for the Blades and I can’t praise him highly enough for what he has done since my arrival.
"He has been a fantastic benefit to the younger lads and in Scotland he was a massive help both on and off the field."
York-born Cresswell joined his hometown team on loan at the end of last season, helping them maintain their League Two status.
