Stoke City boss Tony Pulis has revealed that he is to send a case study to the FA with the hope of some clarification regarding red card tackles.
Potters defender Robert Huth was sent off by referee Martin Atkinson for a tackle on David Meyler in the 1-0 defeat against Sunderland.
Pulis was unhappy with the decision and the club lodged an appeal with the FA, which was rejected. The unsuccessful appeal means the German defender now has to serve a three-match ban and will miss this Saturday's trip to Fulham.
"We are going to put a compilation of incidents together over the next few days," said Pulis.
"We have to clear up what is a sending-off and what isn't, because we are watching games at times and we are getting different decisions being made for different teams and different players, but similar incidents.
"Our big thing is the inconsistency of it all and how we can clear it up."
Stoke are currently 12th in the Premier League after 24 games played.
