Oumar Niasse will serve a two-match ban after his appeal against a diving charge was rejected by the Football Association.
Everton striker Niasse 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.
He was charged by the FA on Tuesday after winning a controversial penalty in Saturday's 2-2 draw at Crystal Palace.
A statement from the governing body 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.
