From Sept 2019 the Surrey Youth League (in line with many other grassroots leagues) will be rolling out the use of Sin Bins for dissent towards Match Officials.

From the start of the 2019/2020 season, all yellow cards for dissent in grassroots football will result in the player being temporarily dismissed from the field of play – or “sent to the Sin Bin.”

If a player commits a first act of dissent, the referee will show them a yellow card and point to the side of the pitch.
The player is required to leave the field of play and is not permitted to re-enter the pitch, or be substituted, until ten minutes of play have passed (eight minutes for all matches of less than 90 minutes). So it will be 8 minutes in any SYL game EXCEPT under 18’s where it will be 10 minutes (even if a double header or game shortened for any other reason) – The time in the sin bin starts when the referee starts their watch (game restarts)
