Preston manager Phil Brown will again be without Sean St Ledger and Leon Cort going into the crunch home clash with relegation rivals Sheffield United.

The central defensive duo remain sidelined with leg injuries as North End host the bottom-placed Blades with both sides knowing defeat would put a massive dent in their survival hopes.

Conor McLaughlin, David Gray and Amine Linganzi are both missing through longer-term injuries and may not feature between now and the end of the season.

Despite sustaining a cut to his head, striker Chris Brown is fit after completing 90 minutes against Doncaster in midweek on his return from injury.

Preston lie one point above Micky Adams` men but seven points adrift of safety with only five matches remaining.

Sheffield United manager Micky Adams could hand late fitness tests to Stephen Quinn, Daniel Bogdanovic and Joe Mattock.

Midfielder Quinn is struggling with a knee injury, striker Bogdanovic is nursing a dead-leg and on-loan West Brom defender Mattock has a slight groin strain, but Adams is still hoping they will be available.

Adams will be boosted by the return to contention of midfielder Lee Williamson, who has served a four-game ban following his dismissal in last month's defeat at Watford.

Strike pair Ched Evans (knee) and Richard Cresswell (groin/Achilles) remain sidelined, but midfielder Nick Montgomery appeared as a substitute in midweek after his wife recently gave birth to twins and could return to the starting line-up.

Teenage defender Harry Maguire made an impressive debut against Cardiff on Tuesday night and will be hoping to at least retain his place among the substitutes.
