Children under the age of 12 will be banned from heading the ball in a trial announced by the Football Association on Monday.
The move will be welcomed by campaigners following research suggesting former footballers are more likely to die from brain disease. The International Football Association Board has backed the trial in England from the start of the 2022-23 season.
It will be put into force by the FA's county network, leagues, clubs and schools throughout the country. A FA spokesman said: "Should the trial be a success, the aim is to then remove deliberate heading from all football matches at U12 level and below from the 2023-24 season."
