Bolton Wanderers manager Owen Coyle has made an impassioned plea for the Football Association's appeals process to be updated.
The Trotters boss is furious that the red card Gary Cahill was handed during Saturday's 4-1 defeat at Arsenal will stand after the club's appeal was thrown out by the FA.
Coyle does not believe Cahill's second-half challenge on Gunners striker Marouane Chamakh warranted the defender being sent off.
However, the FA decided to uphold referee Stuart Attwell's decision and Cahill will now serve a three-match ban, missing the Premier League games against Aston Villa and Manchester United and the Carling Cup clash with Burnley.
Coyle said:"The difficulty with the appeals is the criteria laid down for the panel reviewing the red cards. 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 I spoke to Mike Riley, the head of referees, over the weekend, and he 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."
