Coventry City's Tom Davies has been given a three game ban.
The defender, was adjuged to have stamped on Richard Duffy in the 21st minute of Saturday night's 1-1 draw with Notts County.
Following the incident, which was picked up by the television cameras and not the referee, Davies was charged with violent conduct and has been given a three game ban by the Football Association.
With City not appealing Davies will miss Friday night's second semi-final at Notts County and two more matches which may include the final on May 28th at Wembley if City get there.
Mark Robins is expected to replaced Davies with either Jordan Willis or Rod McDonald for Friday night's game at Meadow Lane which kicks off at 7.45pm.
