Everton striker Oumar Niasse will serve a two-match ban after his appeal against a diving charge was rejected by the Football Association.
The Senegalese becomes the first Premier League player to be hit with a retrospective suspension for simulation under the new law that kicked in at the start of this season.
Niasse was charged on Tuesday by the FA after he won a controversial penalty in Saturday's 2-2 draw at Crystal Palace.
A statement from the FA on Wednesday said: "Everton's Oumar Niasse will serve a two-match suspension with immediate effect after his denial of an FA charge of 'Successful Deception of a Match Official' was rejected.
The ban means Niasse, Everton's top-scorer, will miss the league games at Southampton on Sunday and at home against West Ham three days later.
The FA statement on Wednesday added: "Incidents which suggest a match official has been deceived by an act of simulation are referred to a panel consisting of one ex-match official, one ex-manager and one ex-player.
"Only in circumstances where the panel are unanimous would the FA issue a charge."
