A new rule change next season is set to lead to goalkeepers playing outfield - and vice versa.
It was announced earlier this year that sin bins will be introduced from the fifth step of non-league downwards in place of yellow cards for dissent.
And now more details have emerged of how the rule will be carried out if it applies to a goalkeeper.
Regulations say: "In the case of a Goalkeeper being Sin Binned, an outfield player must take over his position for the ten minute period.
"On completing his/her Sin Bin period, the Goalkeeper must re-enter the field of play as an outfield player, until which time there is a stoppage in play enabling him to change position."
In sending a player to the sin bin, the referee will show a yellow card and point to the touchline, instructing them to take 10 minutes out of the game.
For the temporary period, the player's team will be down to 10 men.
The referee will call the player back on to the pitch while play is going on, similarly to if a player has received treatment for an injury.
Yellow cards for dissent will be used in the totting up process and contribute to bans - but the same player being sin binned twice will not result in their side being permanently reduced to 10 men.
While the player in question will not be able to re-enter the field of play, their manager will be permitted to replace him with a substitute upon the expiry of his 10-minute punishment.
