Ferdinand denies violent conduct charge
The FA's regulatory commission will hear the charge on Thursday, leaving Ferdinand free to face local rivals Manchester City in a League Cup semi-final second leg later on Wednesday. United trail 2-1 from the first leg.
The England international was involved in a clash with Hull striker Craig Fagan in the second half of United's 4-0 win on Saturday.
The match marked Ferdinand's return from a long-term injury which had kept him out since October.
Ferdinand would have collected a three-match suspension had he pleaded guilty but he now runs the risk of a stiffer punishment.
