Bristol City, Enoch Showunmi and his agent have been charged by The FA with misconduct matters relating to the striker's move to the club in 2006.
The club are alleged to have dealt with an unlicensed agent regarding Showunmi's registration and also breaking rules by paying £30,000 to licensed agent Charles Collymore.
The Robins are disappointed they have been charged by The FA and have strenuously denied all the allegations.
"Bristol City Football Club has acted in good faith throughout and co-operated voluntarily with the FA at all times," read a statement on the club's official website.
"The club is very disappointed by their decision to bring these charges and denies the allegations strenuously."
The 25-year-old striker, who has recently been on loan at Sheffield Wednesday, has been charged with engaging the services of an individual who was not a licensed agent or entitled to act in such a capacity.
Collymore has been charged with entering into a sham arrangement with an unlicensed agent regarding Showunmi's registration with the Championship club.
All three parties have until 18th April to respond to the charges.
