Newcastle striker Loic Remy will miss Saturday's derby clash with Sunderland after failing to have his red card at Norwich overturned.
The Frenchman was sent off along with Canaries midfielder Bradley Johnson after the pair clashed late in the 0-0 Barclays Premier League draw at Carrow Road on Tuesday evening.
However, while Remy was unsuccessful, Johnson had his appeal upheld and will be free to play on.
A Football Association statement said: "An independent regulatory commission heard two claims of wrongful dismissal today both in relation to the Norwich City versus Newcastle United game on Tuesday.
"The claim involving Norwich's Bradley Johnson was upheld, meaning his three-match suspension is withdrawn.
"The claim involving Newcastle's Loic Remy was dismissed, therefore his three-match suspension remains with immediate effect.
"Both players had been dismissed for violent conduct."
Loan signing Remy, the Magpies' leading scorer this season, will sit out the league games against Sunderland, Chelsea and Tottenham.
