Fulham have yet to accept a violent conduct charge against Sascha Riether as they want clarification from the Football Association on its retrospective action rule, Press Association Sport understands.
The 30-year-old right-back was charged for stamping on Manchester United's Adnan Januzaj during Saturday's 3-1 defeat at Craven Cottage.
However, despite Riether's admittance of guilt, it is understood the club did not accept the charge before Tuesday's 6pm deadline.
Fulham have instead asked for clarification on certain points of the newly-instigated rules that govern when action can be taken.
