English football will introduce heading guidance across every level of the professional and amateur game from the start of the 2021/22 season.
Headers from long balls, crosses, corners or free kicks will be limited in training for Premier League and EFL players to just 10 per week, under new guidelines for the coming season.
The new guidance was released in a statement from the Premier League.
It follows research that says former footballers are more likely to die of brain diseases, as well as other studies into the impact of heading the ball.
The guidance has been agreed between The FA, Premier League, EFL, the PFA and the LMA and will cover the whole of English football and all its playing members. It will apply to all clubs in the Premier League, EFL, Barclays Women's Super League, FA Women's Championship, the National League System, the Women's Football Pyramid Tiers 3 and below, all grassroots football and across the England national teams.
