The Football Association has charged Leeds manager Neil Warnock with improper conduct for his "on-field behaviour" following his side's 1-0 defeat at Millwall on Sunday.
Warnock was furious that referee Mark Halsey dismissed Luke Varney three minutes into the second half for an apparent elbow on Adam Smith.
A statement on the FA's website read: "Leeds United manager Neil Warnock has been charged by the FA for an alleged breach of Rule E3.
"The charge is in relation to improper conduct following his side's game at Millwall on November 18, 2012."
The 63-year-old has until 4pm on Friday to respond to the charge.
