It is seen as a scourge of the modern game. A goalkeeper goes to ground off the ball and play is stopped. All 10 outfield players rush to the technical area for a team talk.
As soon as the coach has got his new instructions across the goalkeeper gets up. There is nothing a referee can do about it.
It is often used by a coach when their team is struggling, or perhaps they have had a player sent off and need to reorganise.
In November, Leeds United manager Daniel Farke accused Manchester City keeper Gianluigi Donnarumma of feigning injury to “bend the rules”.
An outfield player who has treatment must leave the field for 30 seconds.
The same logic cannot be applied to goalkeepers so the Ifab is considering forcing a coach to remove an outfield player instead.
Some are against it believing it makes the assumption a goalkeeper is cheating when they may be genuinely injured.
The Ifab accepts something has to be done so it is likely to be trialled at lower levels next season and the results evaluated.
But if you think 30 seconds is too much, it might get even longer.
At the Arab Cup last month Fifa trialled players having to leave the field for two minutes if they received attention from the physio.
It is not a new idea, though, and has existed in Major League Soccer in the United States for the last two years.
Players who go down for more than 15 seconds, stay on the floor and get treatment must stay off for two minutes, with a few exceptions.
The Premier League is believed to be against any extension beyond 30 seconds.
