The Blades last game was the 3-3 draw at home to West Ham United, Paul Peschisolido put United ahead after 5 minutes. But goals from Michael Carrick, Jon Harley and Marlon Harewood put the visitors 3-1 up at half-time.
In the second half the home side battled on and to get one back and they did, Paul Shaw rifling home on his debut, Michael Tonge saw his penalty saved before Phil Jagielka headed in a injury time leveller.
Former Nottingham Forest striker Jack Lester will make his first return to the City Ground since his departure last summer. New striker Paul Shaw will not play as he is cup-tied, while former Forest keeper Alan Fettis, who is on loan from Hull City will sit this game out.
Nottingham Forest, who are just 1 point safe of the relegation zone lost there last game 1-0 to Reading at the City Ground.
The Reds have lifted the FA Cup only twice in there history, there first win was against Derby County 1898, ironically the Rams would reach the final the following season but the Blades halted celebrations by beating them 4-1.
They also made the 1959 final when they beat Luton Town 2-1.
Michael Dawson and striker David Johnson came back from a rehabilitation week in Lanzarote this week but are unlikely to be fit for Sunday while Davy Oyen played a reserve game but will also miss out.
Manager Paul Hart is likely to start with the side that lost to Reading but John Thompson could be in for contention.
Man in the Middle: The referee for this Sundays game with Forest will be Phil Dowd of Stoke-on-Trent, he has yet to referee a game for United or for Forest this season.
He has been in charge of 18 games this season, most of them in the Premier League but four Division 1 games and 2 in League Cup. Dowd has dished out 69 Yellow cards and 3 Red cards this season.
