The Football Association has rejected Blackburn defender Stephane Henchoz's claim for wrongful dismissal after his red card against Newcastle on Saturday.
Henchoz was sent off in the first half
Henchoz will now serve a one-match ban and miss Rovers' Premiership game against Reading this weekend.
Referee Dermot Gallagher dismissed Henchoz for a professional foul.
Gallagher decided Henchoz had denied Magpies striker Obafemi Martins a goalscoring chance when he headed clear but fouled him in the process.
Newcastle, who were leading 2-0 at that stage, won the match 3-1 at Ewood Park.
