This will continue to go on until the official time on the field is kept OFF the field! When there is a goal, the clock should stop until the ref blows the whistle for the restart of the game. When the ref stops play for an injured player, the clock should be stopped...
With the "game clock" clearly visible to everyone, it would make all the rolling around just an attempt to get a player carded, and we'd all be able to see it for what it is.
And, while I'm on about it, it is long past time there was retrospective action for all the fakery. Players who are clearly NOT touched in the face, but who go down clutching their face, should be given a seat in the stands for the next game. It is a cancer in the game and the egregious examples make football look like a game of fakers, soft arses and cheats!
