Leeds will attempt to minimise their penalty, however, during a personal hearing, which is yet to be arranged by the FA but is not expected to be held before the end of the Championship season, and the Professional Footballers' Association have agreed to support United's mitigation.
The club already have a suspended £60k fine hanging over them, imposed by the FA for their poor disciplinary record last season, but the suspension will not be affected by United's latest charge.
Chief operating officer Shaun Harvey said: "We've pleaded guilty to the charge but we have also requested a personal hearing where we will put forward our mitigation. The club have secured the support of the PFA who, along with ourselves, will represent our case at a date which is as yet unknown.
"The charge has no bearing on the suspended £60,000 fine previously imposed by the FA."
