Burnley defender Clarke Carlisle has lost his appeal against the red card he received against Millwall on Saturday.
Carlisle was dismissed by referee Keith Stroud following a challenge on Theo Robinson and was shown a straight red inside the opening 10 minutes at the New Den.
The 30-year-old centre-half will now serve a three-match ban and miss the Championship games with Sheffield United, Barnsley and Reading later this month.
Having watched footage of the incident in the aftermath of the 1-1 draw, the Clarets opted to appeal against the decision but a Football Association commission has rejected their attempt.
Manager Brian Laws told the club's official website: "We are disappointed with the outcome.
"We felt the decision was harsh but be have to accept the verdict and move on.
"We again showed on Saturday the strength we have within the squad and I know that whoever benefits from Clarke's absence will come in and do a good job for us when we start again after the international break."
