Premiership giants Newcastle United will provide the opposition for Chris Morgan's testimonial fixture, which will take place in July.
The popular former skipper has used his relationship with current Magpies chief John Carver, who was a coach with the Blades during Gary Speed's time in charge of the Club before rejoining his boyhood team.
The eagerly-anticipated game, which is expected to see the top flight outfit travel in big numbers, will be played at Bramall Lane on Sunday 26th July, kick-off 1pm.
Morgan, who has always worked with the Club in supporting the local community and charities during his time as a Blade, both in a playing and non-playing capacity, will be donating funds from the game to three very worthy local organisations, full details of which will follow.
The former skipper is keen to thank Carver and Newcastle United Managing Director Lee Charnley for making this plan become a reality.
Morgan remarked: "It promises to be a brilliant fixture and one that should benefit both clubs in pre-season preparations, in addition to three really important local charities.
"But it wouldn't have been possible without the massive help of JC and Lee, who despite having more important things on their minds in recent weeks, have stuck to their word about going ahead with the fixture if Newcastle preserved their top-flight status.
"They are touring the USA and their fixture against us will be their first back on English soil upon their return so I am sure, like they always do, their fans will come down from the north-east in large numbers.
"For us, it will give the new manager a chance to experience Bramall Lane as the home Gaffer before the season starts in August and it will be an important occasion with that in mind."
Morgan signed for the Blades in the summer of 2003, went on to play 279 games, winning promotion to the Premiership as skipper in 2006, before joining the coaching staff when injury prematurely ended his playing days.
Ticket prices and other details surrounding the testimonial fixture will be announced in due course.
This is United's first confirmed pre-season friendly, but following the appointment of new manager Nigel Adkins, it is hoped a full and comprehensive list of friendly fixtures will be announced shortly.
