The FA has asked Leicester City manager Nigel Pearson to explain his comments after last Saturday's controversial home draw against Nottingham Forest.
A letter has been sent to Pearson asking him for his view on what he said to the media following referee Anthony Taylor's decision to award Forest a hotly-disputed penalty.
Pearson has until the end of Monday to respond and the FA will then decide whether or not to charge Pearson.
Taylor penalised Zak Whitbread for a challenge on Billy Sharp inside the City penalty area in the second half of a game City had under control and Simon Cox stroked home the spot-kick to give Forest a 2-2 draw.
The City boss was livid with the decision, which cost his side two points, and branded it "laughable".
"It was never a penalty and we were robbed of two points," he said. "I am under scrutiny and the players are under scrutiny, and it is about time these people were held accountable for their decisions.
"I am not going to waste my time trying to talk to people who are totally disinterested with what is right and what is wrong.
"They have a team of four people out there and they need to utilise all four of them. For me, it is laughable."
