Reading are set to appeal against the red card shown to Jimmy Kebe during their 1-0 win at Barnsley on Saturday.
The Royals informed the Football Association of their desire to question the decision before Monday's deadline and will submit further paperwork supporting their case on Tuesday.
The appeal will then be heard on Tuesday afternoon, when a verdict will be reached.
Kebe was dismissed towards the end of the first half at Oakwell for allegedly tangling with Tykes defender Dennis Souza.
The Barnsley man made no complaints regarding the attention he had received, with Reading at a loss to explain the resulting sending off.
"You can see the Barnsley player who was involved and his reaction is clear," Reading's director of football Nick Hammond told the club's official website.
"Steve Coppell also had a clear view and believes it was very harsh and unfair. We are not the sort of club to make frivolous appeals."
Should Kebe's automatic three-match suspension stand he will be forced to sit out home games against Blackpool and Norwich and an away trip to Birmingham.
