The Football Association has rejected Norwich City's appeal against the red card shown to Jonny Howson over the weekend.
The midfielder was sent off for a rash challenge against Bournemouth on Saturday and will now serve a three-game ban.
He will miss the upcoming Championship games against Cardiff City, Brentford and Birmingham City.
Howson was dismissed with the score at 1-1 against the league leaders, but Norwich found a late winner to end Bournemouth's 14-game unbeaten run and move within a point of the playoffs.
