The Blades are now in 5th position after that timely 2-1 win over Cardiff at the Lane which saw both Andy Liddell and Andy Gray overturn Neil Harris first half strike.
United don't have fresh injury worries but Neil Warnock will have to decide weather to sacrifice Paul Shaw who could face being replaced by either Danny Cadamarteri or Luke Beckett.
New defender Danny Cullip is likely to receive his second start for the Blades. keeper Ian Bennett will remain in goal as Paddy Kenny sits out the last of his three match suspension.
Predicted Blades XI: Ian Bennett, Leigh Bromby, Danny Cullip, Phil Jagielka, Chris Morgan, Derek Geary, Jon Harley, Michael Tonge, Alan Quinn, Paul Shaw, Andy Gray.
The Sky Blues, in 18th place also go into this game on a high having beaten Watford 1-0 with a Gary McSheffery goal.
Peter Reid's team welcome back Midfielder Michael Doyle who missed that 1-0 victory whilst Adrian Williams could feature after overcoming an hamstring injury.
They will however be without young defender Andrew Whing who has recently undergone surgery to cure a hernia problem.
Predicted Sky Blues XI: Luke Steele, Richard Shaw, Louis Carey, Syuart Giddings, Florent Laville, Isaac Osbourne, Stephen Hughes, Stern John, Andy Morrell, Dale Adebola, Gary McSheffery.
