Everton have submitted an appeal to the Football Association after Tim Cahill was sent off in Saturday's derby defeat by Liverpool.
Cahill was shown a red card by referee Mike Riley in the closing 10 minutes of the 2-0 loss after a challenge on Xabi Alonso.
Toffees manager David Moyes was unhappy with Riley's decision after the game, believing the midfielder's tackle only warranted a yellow card.
"I have had a chance to look at it and I don't see a red card tackle, I really don't," said Moyes at the time.
"I see a yellow card and I don't think it was the worst tackle in the game. I think we were all really surprised it was a sending off."
The club have now confirmed that an appeal has been lodged with the FA, with a hearing due to take place later this week.
If Cahill's appeal fails, the Australian will miss Everton's next three Premier League games against Newcastle United, Arsenal and Manchester United.
