The only absentee from Saturday's starting X1 will be Arthur Gnohere. The loan defender will miss out as Burnley won't let him play. The most likely replacement is for Steve Palmer to drop back to defence and allow Mark Bircham to return to midfield and anchor the team alongside Marcus Bean.
Terrell Forbes is also in contention however after playing at centre-back for the reserves last week and Holloway confirming he wants to give him a chance in that position.
Tony Thorpe is also unavailable (cup-tied) having played for Luton in the first round.
Whatever the team, it will be a very tough for Rangers against a side who reached both cup semi-finals last term and as well as Rangers endured a heart-ache playoff final defeat.
Neil Warnock is set to make wholesale changes after being refused permission to play Jon Harley or Paul Gerrard- both loan signings.
Kristian Rogers is set for a debut in goal and Michael Brown returns from a suspension. Chris Armstrong is likely to replace Harley on the left and summer signing from Tranmere Andy Parkinson is set for a first start. Chris Morgan, Robert Page, Paddy Kenny and Steve Kabba are all still missing for the Blades.
Warnock also said he may use this game to offer a chance to youngsters and fringe players.
Rangers will go into the game as heavy underdogs but there is no doubting the visitors' ability to spring a suprise, with plenty of players with experience at a higher level available to Ian Holloway.
