Luton captain Kevin Nicholls has been charged by the Football Association with improper conduct.
Nicholls has been charged following an incident after the controversial 3-3 draw with Bradford at Kenilworth Road on January 24.
The midfielder has until February 23 to respond to the charge, which adds to those already handed to the League Two club.
The Hatters have already been charged with failing to control their players after referee Trevor Kettle awarded a controversial late penalty to the Bantams.
And manager Mick Harford faces a charge of improper conduct following his alleged behaviour towards Kettle, while opposite number Stuart McCall has been charged with misconduct after being dismissed from the dugout.
