Arsenal's appeal against Dennis Bergkamp's dismissal last Saturday has been dismissed, the FA has said.
The Dutch forward was sent off for pushing Sheffield United's Danny Cullip in the 35th minute of the FA Cup fifth round tie but Arsenal appealed, TV pictures suggesting it might not have been his hand which made contact with the defender.
"A disciplinary commission has rejected a claim for wrongful dismissal from Arsenal FC in relation to Dennis Bergkamp," the FA said in a statement on their website on Wednesday.
"A three-match suspension will start with immediate effect."
Bergkamp will miss the English Premier League match at Southampton on Saturday, the replay against Sheffield United on March 1 and the home league match against Portsmouth the following weekend.
His team mate Jose Antonio Reyes was also charged with violent conduct following the incident and had until 1800 GMT on Tuesday to admit or deny the charge.
