Amateur footballers in Birmingham could be among the first in the world to be sin binned.
During the 2017-18 season the Birmingham and District Football League will be one of 32 competitions trialling the alternative to yellow cards for dissent.
Players will be given ten minutes on the sidelines instead of picking up a caution as part of the pilot project.
The Football Association says it hopes the changes could result in fewer bookings.
Mark Ives from the FA said: “I am encouraged by the level of enthusiasm from leagues, clubs and referees and in their collective commitment to make a difference to our great game at a local level.
“I look forward to seeing a positive impact during the course of the season.”
The changes come after figures revealed that dissent accounted for a quarter of all bookings during the 2016/17 season.
