Celtic boss Neil Lennon has been issued with a notice of complaint over alleged rule breaches relating to the Scottish Cup defeat by Hearts, the SFA have announced.
Lennon has been hit with a misconduct charge, which relates to offences including aggressive behaviour and insulting language towards a match official.
He confronted referee Euan Norris over a penalty award, which came when a Hearts' shot hit the arms of two Hoops players.
Celtic were then denied a penalty when the ball struck a Hearts defender.
Lennon has also been hit with two charges relating to comments made on Twitter.
The Hoops boss, who did not conduct any post-match interviews, tweeted soon after the game: "Referee told players he thought Wanyama handled...feel so sorry for players and fans..I think it's personal myself."
He then re-tweeted a comment from a Celtic supporter which suggested the club "pack our bags and get out of this league that is run by crooked #SFA officials".
The online comments will see him face two charges, including an alleged breach of rule 68 which forbids criticism of match officials in a way that indicates bias or incompetence or impinges on his character. The rule specifically includes comments made on a "social networking or micro-blogging site".
Lennon is also accused of breaching rule 71 by not acting in the best interests of football or acting in an improper manner.
