Lee Hendrie returns to contention for Sheffield United after missing the derby defeat to Sheffield Wednesday.

The former Aston Villa midfielder sat out last week's derby disappointment at Hillsborough due to a one-game ban, but is pressing for a return to the starting line-up on Sunday.

New permanent signing Ugo Ehiogu is pushing for a start after remaining on the substitutes' bench last week, while Gary Naysmith could also return to the side following his shoulder injury.

Manager Bryan Robson, who has no new injury or suspension problems, must decide whether to recall Keith Gillespie and Billy Sharp to the starting line-up.

Long-term absentees James Beattie, Danny Webber (both knee) and defender Chris Morgan (ankle) remain sidelined as the Blades chase a morale-boosting Cup win.

Manchester City defender Micah Richards is out of Sunday's FA Cup fourth-round tie at Sheffield United with a knee injury.

Midfielder Javier Garrido is also sidelined through illness, but Emile Mpenza at least returns to strengthen the striking options after a five week lay-off with a hamstring problem.

With Nery Castillo recovering after a shoulder injury and Rolando Bianchi joining Lazio on loan this week, manager Sven-Goran Eriksson has added another striker to the squad in 18-year- old Daniel Sturridge.
