Sheffield United boss Kevin Blackwell has a number of injury concerns to contend with ahead of the visit of Bristol City.
Goalkeeper Mark Bunn is expected to be sidelined for around six weeks with a broken hand so Ian Bennett will continue in goal.
Defender Chris Morgan is not likely to return for a fortnight due to a rib injury, while fellow centre-half Marcel Seip (hamstring) is also out.
On-loan Arsenal youngster Kyle Bartley impressed in the 2-1 defeat to Preston on Tuesday and is set to keep his place
However, defender Andrew Taylor is available after a hamstring injury and set for at least a place on the substitute's bench.
Midfielder James Harper continues to struggle with an ankle injury and is set to see a specialist to determine the extent of the injury.
City are plagued by injury and illness ahead of the trip to Sheffield.
Striker Nicky Maynard, winger Jamal Campbell-Ryce and midfielder Danny Haynes all remain in the treatment room after missing Tuesday's defeat at Watford.
Maynard has a dead leg, Campbell-Ryce is nursing a calf problem and Haynes is unwell.
Jamie McCallister sustained a calf injury at Vicarage Road and he will not travel north, while Johnson has revealed that another unnamed player has come down with an illness.
Jamie McCombe and Brian Wilson remain long-term absentees so Johnson may be forced to scour the loan market ahead of the clash.
"We find ourselves a little short for Saturday," he told the club's official website.
"I'll have to ring around a few clubs and speak to the chairman to see if there's anything we can do to fix that."
