PFA chief executive Gordon Taylor believes there is a need for a review panel following Callum McManaman's tackle on Massadio Haidara shows the need.
McManaman escaped punishment during Sunday's Premier League game despite a high challenge, which forced Newcastle United's Haidara off with a knee injury, and the Football Association is unable to take retrospective action.
"I feel there is a need for a review system," Taylor told Sky Sports News.
"We have been asking for some time for a panel of experienced people from within the game to look on a Monday morning at simulation, any abuse or tackles or red cards.
"I think there is going to be a similar inquiry into how we can deal with a situation when the referee says he has not seen it and the assistant referee was quite some way away from it."
Taylor added: "There is an overriding principle that the referee has got to be in charge of it.
"But I think that when we have technology there has got to be an ability to look at things with a few views of the incident and then take appropriate action if necessary for the good of the game."
