Celtic manager Neil Lennon has been called to appear before the Scottish FA to explain alleged misconduct during Sunday's loss to Rangers at Ibrox.
Lennon was sent from the technical area after a half-time confrontation with referee Calum Murray in the tunnel.
The manager said after the match that he was prevented from doing his job and could not understand the decision.
Meanwhile, Celtic will appeal against Cha Du-Ri's red card during the first half of the Glasgow derby.
Cha was adjudged to have committed a professional foul on Lee Wallace when he was sent off in the 29th minute.
A date for Lennon's hearing has been set for 19 April and the manager has until 3 April to respond to the notice of complaint.
The notice relates to the SFA's Rule 203 which states: "No member of Team Staff shall commit Misconduct at a match" where misconduct can be regarded as "dissent, the adoption of aggressive behaviour towards a match official and the repeated use of offensive, abusing and insulting language."
