Everton striker Oumar Niasse will serve a two-match ban after his appeal against a diving charge was rejected by the English 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 English FA after he won a controversial penalty in Saturday's 2-2 draw at Crystal Palace.
A statement from the English FA yesterday 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.
"It was alleged he committed an act of simulation which led to a penalty being awarded in the fifth minute of the game against Crystal Palace on 18 November 2017.
"He denied the charge, however, it was found proven following an Independent Regulatory Commission hearing today (Wednesday 22 November 2017)."
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. Meanwhile, Yannick Bolasie trained with his Everton team-mates yesterday as the winger stepped up his rehabilitation from a long-term knee injury.
The session at Finch Farm, ahead of tonight's Europa League clash with Atalanta, saw Bolasie training with the senior Toffees squad for the first time since sustaining anterior cruciate ligament damage to his right knee on December 4 last year.
Everton caretaker boss David Unsworth hopes the DR Congo international could make a return to action by the new year.
Club captain Phil Jagielka and fellow defender Morgan Holgate were notable absentees from the session, along with midfielder Morgan Schneiderlin.
Jagielka, 35, played the whole of Saturday's 2-2 Premier League draw at Crystal Palace, while Holgate was missing from the squad. Schneiderlin, suspended for Thursday's match, was substituted at half-time.
He was red carded in the last Europa League outing, the 3-0 loss at Lyon on November 2, when it was confirmed Everton, who are bottom of Group E, would not be able to qualify for the next round.
