All football players in England will have to stick to new rules about heading the ball from the start of the 2021/22 season.
The main rule is that professional players will only be able to do a maximum number of 10 high impact headers in any one training week. Higher force headers include ones from a long pass, cross, corners or free kick.
This includes footballers from the Premier League and the Women’s Super League, right down to children.
The new rules have been made to try and protect players from health problems associated with headers.
In 2019, a study found professional footballers were more likely to suffer from brain diseases later in life and it is thought heading the ball might be one of the reasons this happens.
The FA suggest that headers are practised using lower impact ways, for example when the ball is thrown to the player rather than kicked.
