Derby manager Frank Lampard has accepted a charge of improper conduct from the Football Association (FA) following his sending-off during his side's defeat at Rotherham on Saturday.
The former Chelsea and England midfielder was sent from the dugout in the 77th minute of the Rams' 1-0 loss at the New York Stadium.
Lampard had left his technical area to complain about a decision and was swiftly dismissed by referee Peter Bankes.
Derby County were trailing at the time following a Ryan Manning penalty.
They were also down to 10 men Tom Lawrence was sent off for a late tackle on Richie Towell.
Lampard initially said he felt he was unfairly sent off.
But, speaking at a re-match press conference for Derby's clash with Blackburn Tuesday (September 18) he said: "I'll accept the fine and we'll move on.
"Some of the frustration comes because we didn't play as well as we could on the day."
