West Ham United striker Andy Carroll will serve a three-game ban after having an appeal against a red card rejected, the Football Association announced on Tuesday.
Carroll, 25, was shown a straight red card during his side's 2-0 win over Swansea City on Saturday after catching Chico Flores in the face with his arm early in the second half of the English Premier League game at Upton Park.
West Ham manager Sam Allardyce accused Flores of reacting theatrically and confirmed that the club would appeal against the red card, but the FA upheld referee Howard Webb's decision to send Carroll off.
"West Ham United's Andy Carroll will serve a three-match suspension with immediate effect after his claim of wrongful dismissal was rejected by an Independent Regulatory Commission," read a statement on the FA website.
"As stated in the Rules and Regulations of The FA, an Independent Regulatory Commission must apply the test of whether the decision to dismiss a player was 'an obvious error'.
"The decision of an Independent Regulatory Commission in relation to a claim of wrongful dismissal is final and binding on all parties and is not subject to appeal."
West Ham's record signing, Carroll has played in only four league games this season due to injury and now stands to miss his side's forthcoming matches against Aston Villa, Norwich City and Southampton.
