Bolton manager Owen Coyle believes the appeals process must be looked at by the Football Association.
The Trotters this week contested the red card shown to Gary Cahill for a challenge on Marouane Chamakh in Saturday's defeat to Arsenal.
However, the FA decided to uphold referee Stuart Attwell's decision and Cahill must now serve a three-match suspension, missing the Premier League games against Aston Villa and Manchester United and the Carling Cup clash with Burnley.
Coyle still does not believe that Cahill deserved to be dismissed for a foul that he feels warranted a yellow card, and has called for the whole process to be reviewed to ensure justice is done.
"The difficulty with the appeals is the criteria laid down for the panel reviewing the red cards," he explained.
"Some of the text says it needs to be a clear and obvious mistake by the referee; if it's a yellow card it's not clear and obvious because it's just an interpretation.
"Maybe the criteria needs to be looked at because any football person that looked at that... I spoke to Mike Riley, the head of referees, over the weekend who also felt it was a yellow card.
"When you've got somebody of that calibre saying that, it reinforced my belief there was a chance it would be overturned."
Cahill could be joined on the sidelines by Kevin Davies for this weekend's encounter at Villa Park.
The striker has sat out training this week following a clash of heads with Arsenal defender Laurent Koscielny and Coyle will not take any risks if he has not fully recovered.
The manager said: "He hasn't trained all week and he won't train today. We'll have to monitor that one. Because it was a head knock it's of paramount importance that he's OK.
"Nobody wants to win games more than me but we'll not take a chance with any of our players' health.
"We'll give Kevin until the last minute but ultimately we have to make sure he's 100 per cent."
