Everton have had two appeals against midfielder Allan's red card in the 1-0 win over Newcastle rejected.
The Brazilian was shown a yellow card by referee Craig Pawson after bringing down Allan Saint-Maximin on Thursday.
But, after the video assistant referee (VAR) told him to review the foul on a monitor, Pawson upgraded it to red.
Everton said their "request to overturn that decision was rejected" along with "a second appeal to downgrade the ban for excessive punishment".
Allan will now miss the Goodison Park club's FA Cup quarter-final against Crystal Palace on Sunday, and Premier League games at West Ham and Burnley.
