Sheffield United (5) v Coventry (20)
Sheffield United boss Nigel Clough could be tempted to name an unchanged side after three successive wins.
Number-two goalkeeper Iain Turner is set to start while Ryan Flynn and Michael Higdon are unlikely to recover in time.
Jose Baxter (dead leg) and Stefan Scougall (knee) are also injury concerns.
Hamstring injuries mean Frank Nouble and Reda Johnson are still out for Coventry.
The same problem is troubling on-loan forward Sanmi Odelusi but Andy Webster (shoulder) is back training and Blair Turgott is set to be in the squad.
