Sheffield United boss Neil Warnock has admitted a charge of improper conduct by the Football Association.
Warnock's Blades team are eyeing promotion from the Championship
Warnock was hit with the charge over a gesture he made towards the Norwich bench after the final whistle of their match at Carrow Road on 18 March.
The 57-year-old was incensed that Norwich counterpart Nigel Worthington ignored him, refusing a handshake after the Canaries' 2-1 victory.
Warnock has also requested a personal hearing regarding his charge.
The Blades boss had previously said: "When the governing body looks at the incident I think they will decide to take no action.
"I won't deny that I flipped my fingers in his direction but only because I was so disgusted and frustrated at being humiliated by a fellow manager.
"If the same circumstances arose I would do the same again.
"I held out my hand for six or seven seconds but he kept on talking and turned his back. There was no mix-up, he even looked me in the eyes.
"I am sorry if it upset any fans. There was definitely no offence intended to anyone inside the ground apart from their staff."
