Stoke manager Tony Pulis is seeking clarity from the FA on tackling following Robert Huth's sending-off against Sunderland.
Potters defender Huth was shown a straight red card by referee Martin Atkinson in the first half of the 1-0 Premier League defeat at a snowy Britannia Stadium for a sliding challenge on David Meyler.
Atkinson's decision left Pulis fuming and the Staffordshire outfit subsequently lodged an appeal with the FA but it was rejected, meaning Huth - now hit with a three-match ban - will sit out the trip to Fulham.
The Welshman intends to pursue the matter, though, and said: "We are going to put a compilation of incidents together over the next few days.
"We will do it very professionally, in a proper manner, and then we'll send it off to the FA.
"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. There is no point being just negative with it - you have to be a little bit constructive with it as well. We are disappointed that it (Huth's red card) has not been rescinded, but we have to get on with it."
