Leicester City 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 swear at a supporter 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 boss Nigel Pearson believes his current squad boasts plenty of top-flight potential as the Foxes look to take another giant stride back towards the Barclays Premier League on Friday night.
Pearson said: "We have some quality at this level and I believe a lot of our players are capable of making the step up when we achieve that.
"It is all right having good players but they have to be the right sort. They have to have the same goals and when things get tough, they have to be prepared to keep those values going.
"You can't build a team overnight. It has taken time to build a squad of players good enough."
Nigel Pearson says while the fans have supported Leicester City throughout the season but the club needs to deliver.
