Leicester goalkeeper Kasper Schmeichel will miss four to six weeks with a broken metatarsal, manager Nigel Pearson has said.
Leicester full-back Paul Konchesky's red card against Aston Villa on Sunday has been rescinded.
The 33-year-old was dismissed by referee Craig Pawson following a clash with Villa defender Alan Hutton in the Foxes' 2-1 defeat at Villa Park.
A Football Association statement read: "Leicester City's Paul Konchesky, who was dismissed for violent conduct in the game against Aston Villa on December 7, 2014 will not serve a suspension after a claim of wrongful dismissal was upheld following an Independent Regulatory Commission hearing today."

Leicester manager Nigel Pearson has been asked for his observations by the Football Association after an exchange with a supporter during last week's loss to Liverpool, the governing body has said.
Pearson appeared to tell a supporter to "f*** off and die" after he was subjected to verbal abuse from the person in question.
It is a routine move from the FA and Pearson has until 6pm on Wednesday to come back with his observations for the governing body to look at.
He refused to apologise to the fan despite calls from the Leicester City Supporters Club to say sorry after a video emerged of the argument.
– Leicester manager Nigel Pearson
I have had run-ins with fans in the past and in the heat of the moment these things happen and there won't be any apology. Let's put it like this, it's best if we don't speak about what happened on either side, I'm not going to repeat what happened here.
I am very keen to protect my players and myself and I'm more than happy to stick up for myself in that situation and, more importantly protect my players, that's the root cause of the problem.
If people were offended by what happened in some ways that is regrettable but there's no need for me to apologise to someone of that ilk.
Leicester captain Wes Morgan is suspended for the match at Aston Villa in the Premier League on Sunday.
The defender was sent off against Liverpool and will sit out for a game at Villa Park.
David Nugent is a doubt with illness which has affected some of the squad but manager Nigel Pearson, who did not name others who were laid low, hopes any bug would have cleared by Sunday.
Provisional squad: Schmeichel, Hamer, Moore, De Laet, Konchesky, Wasilewski, Drinkwater, James, King, Cambiasso, Albrighton, Mahrez, Knockaert, Vardy, Ulloa, Nugent, Schlupp, Wood, Powell.
Leicester City Supporters Club chairman Cliff Ginnetta has insisted they do not want Nigel Pearson's fan row played out like a "pantomime".
Ginnetta believes the majority still back the Foxes boss despite his angry exchange with a supporter on Tuesday and want to focus on beating the drop.
The Leicester chief rowed with a fan during their 3-1 defeat to Liverpool which left them bottom of the Barclays Premier League.
– Leicester City Supporters Club chairman Cliff Ginnetta
He should put his hands up, admit he was out of order, apologise to the people and move on, that's all everyone wants.
We don't want to make it a big thing or play it out like a pantomime, we just want to get on with winning games.
I'm sure the majority do (still support him), people are worried and moaning but that's football fans, you're never really happy. It's the nature of the beast.
If you looked after the QPR game (a 3-2 defeat) there was no booing or shouting, they were applauding them off, the fans are right behind him and he has to remember that. He is popular but this arrogance spills over sometimes.
