The MMP Central Wales League is one of six grass roots football leagues across Wales to trial temporary dismissals, commonly known as “sin bins” next season.
During the trial, players will be shown a blue card for dissent and must leave the pitch for a 10-minute period.
Sanctions for all other offences will remain unchanged.
The decision was approved by The FAW’s Community Game Board following discussions with the six Area Associations.
The leagues involved, clubs, coaches players and referees will receive training on Temporary Dismissals before the start of the 2023-2024 season.
Noel Mooney, CEO of the FAW said: “Our mission is to make football the most inclusive, accessible and successful sport in all parts of Wales. The Temporary Dismissals trial will help us achieve our aim by encouraging fair and respectful behaviour in grassroots football which will only increase participation and strengthen the game as a whole."
Chairman of the FAW Community Game Board Mark Adams added: “We have an ambitious plan to increase the number of match officials across Wales to service the incredible growth of grassroots football. However, dissent and abuse towards match officials has been identified as a key reason for referees leaving the game.
"A similar Temporary Dismissals trial period in England saw a 38 per cent reduction in cautions for dissent. By introducing Temporary Dismissals, we hope to reduce dissent and abuse towards match officials and therefore increase the number of referees available to help develop grassroots football in Wales.”
The other five leagues to trial the system are: North Wales Coast East Premier Division, North East Wales Reserve League, Highadmit Projects South Wales Alliance League, Macron West Wales Premier League and the Gwent Premier League.
English grassroots football introduced sin bins in 2019.
