The idea of sin bins in football has been knocking around since, it feels, the beginning of time.
But now, it appears to be happening. Or at least moving a step closer, with the International Football Association Board (IFAB), the sport's lawmakers, recommending this week that "temporary dismissals" should be trialled in professional football, beyond the grassroots levels where they have already - successfully, apparently - been tested.
"The areas we're looking at is dissent and tactical fouls," said Mark Bullingham, chief executive of England's Football Association, which, along with the world game's governing body FIFA and the FAs of Scotland, Northern Ireland and Wales, makes up IFAB. "There is real frustration with fans when they see a counter-attack that is ruined by that and whether a yellow card is sufficient."
"So, the starting point was really looking at player behaviour and dissent but then looking at whether we should extend it into other areas such as tactical fouls as well."
He added: "If that's the way the protocol goes then, absolutely, you spend potentially 10 minutes off the pitch as well.
"Some players do commit a foul - I know people call it a tactical foul, cynical foul, professional foul – but a foul that prevents a promising attack and they do it consciously knowing they're going to get a yellow card, and we think that really breaks up the game. So, would they not do it if they felt there was going to be a sin-bin? And that would be the question. I think with all of these things, success of sin-bins in grassroots game has been prevention, rather than cure. You get to a point where players know the threat of sin-bins and, therefore, don't transgress. And we would hope that it would make the same change."
In the trials to have taken place so far, a sin-binning is indicated by the referee showing a yellow card, then pointing to the sidelines with both index fingers, banishing the offending player to the sidelines for 10 minutes.
What do you think if this does happen?
