Leicester midfielder Lee Peltier remains sidelined by the groin injury he sustained at Coventry and looks unlikely to recover in time to face Bristol City.
The midfielder scored the winning goal at the Ricoh Arena and missed Saturday's 2-0 defeat to Reading.
Striker Darius Vassell misses the final game of his three-match suspension, leaving David Nugent and Jeffrey Schlupp poised to keep their places in Sven-Goran Eriksson's frontline.
Forward Martyn Waghorn is pushing for a start following a substitute appearance at the weekend.
Waghorn told the Leicester Mercury: "I am going to keep fighting. It is not over for me yet.
"I want to play football and I am young. If I get 15 minutes I have to do my best in that time to show what I have got."
Bristol City's defensive woes will not be helped by the absence of Liam Fontaine for the trip to the East Midlands.
Fontaine has not played since the Robins' 3-0 opening day defeat to Ipswich after suffering an ankle injury.
The 25-year-old defender, who has been at Ashton Gate for six years, was expected to return for Sunday's fixture with Cardiff but missed the 3-1 reverse after having an injection in the troublesome ankle.
Right-back James Wilson made his debut against the Bluebirds in place of Fontaine and could start again at the King Power Stadium.
But Robins boss Keith Millen is more likely to call upon the more experienced defender Louis Carey, who should be back in contention after his recovery from an illness.
Carey boasts the second highest number of appearances for the club and will be looking to add to that with his first appearance of the new campaign.
Damion Stewart has emerged as a late doubt after the former QPR defender suffered a knock in training on Monday.
Stewart was unable to train on Tuesday so will undergo a medical check before the team travel.
Stewart was an unused substitute for his side's 3-1 defeat at Cardiff on Sunday but Millen has confirmed he is a major doubt for Wednesday's game by telling the club's official website: "We'll check on Damion before we head to Leicester.
"Aside from that we're looking alright injury-wise, but it does mean our options are a little limited at the back."
