Everton manager David Moyes has been charged with improper conduct following his full-time reaction to Saturday's 3-3 draw with Manchester United.
Moyes and his assistant Steve Round, who has also been charged by the Football Association, ran onto the pitch and confronted referee Martin Atkinson.
The pair were aggrieved that, having seen their side snatch two stoppage-time goals to claw back United's lead, Atkinson blew up for full-time while the Toffees were counter-attacking.
Phil Jagielka's shot was saved by Edwin van der Sar but Atkinson still felt the wrath of the Toffees management team as he attempted to leave the Goodison Park pitch.
Speaking immediately after the late flashpoint, Moyes was furious at the timing of the whistle, saying:"It is a spectator sport with people coming to watch the game and not for him to be the main man and the one who wants to be seen making the decisions.
"That was a terrible decision in my book."
Moyes and Round have now been given until Tuesday to answer the improper conduct charge.
An FA statement read:"Everton manager David Moyes and assistant manager Steve Round have both been charged with improper conduct.
"The charges relate to Moyes' and Round's conduct towards referee Martin Atkinson on the pitch following the final whistle at Everton's home match against Manchester United on September 11.
"Under the FA's new fast-track procedures, Moyes and Round have until Thursday, September 16, to respond to the charges and have both been offered a standard sanction of an £8,000 fine should they accept the charge.
"If either party denies the charge, the case will be heard by a regulatory commission within 10 working days."
