Leicester City will be without Matt Fryatt for their next three games after his suspension was upheld.
The 21-year-old was dismissed in last weekend's 2-0 victory over Bristol City in manager Ian Holloway's first game in charge of the club.
Leicester had hoped to have his mandatory three-game ban reduced, however, their appeal has been rejected.
Fryatt will now miss the club's upcoming Championship games against Southampton, Burnley and West Brom.
The young striker, who has three goals to his name this season, played the full 90 minutes of Monday's goalless draw with Cardiff.
