Reading have had a fine for misconduct in relation to supporter behaviour reduced by £60,000 by a Football Association appeal board.
The Royals were hit with a £100,000 punishment in August for failing to prevent a pitch invasion during the FA Cup quarter-final replay against Bradford City in March.
Despite saying that they were "pleased" to have the fine reduced to £40,000, Reading also said that they were "disappointed" with the initial decision to punish them.
"After a total of 16 other celebratory pitch incursions took place at other stadia across the country last season, we were the only club penalised.
"Reading Football Club are regularly among the clubs with the lowest number of arrests and banning orders in the division and we are also very proud of our supporters' reputation for good behaviour, both at home and away, as a club we remain disappointed by the decision and feel that the processes undertaken by the Regulatory Commission in these situations need to be reviewed in the future."
Reading fell to eventual winners Arsenal in the semi-finals.
