Aston Villa have confirmed they will appeal against the red card shown to Gabby Agbonlahor during Saturday's 1-1 draw at home to Manchester United.
The striker was sent off in the second half for a challenge on Ashley Young.
Speaking after the match, manager Paul Lambert told the BBC: "I didn't think it was a sending off.
"Ashley Young has said to Brad Guzan that he made the foul on Gabriel Agbonlahor. That was not a sending off, everyone in the ground saw that."
It was the second consecutive match in which a Villa player was shown a red card, following Kieran Richardson's dismissal against West Bromwich Albion on 13 December.
Aston Villa are currently 12th in the Premier League, having picked up seven points from their last four league games.
Lambert's side travel to eighth-placed Swansea on Boxing Day, before hosting Sunderland on 28 December.
