New study shows heading a hard or soft ball 20 times in a short period of time is enough to cause people to fail head injury tests which would stop them being able to play
Hard and soft balls had similar effects 10 of the participants headed balls with a PSI of around 8, while the other 10 headed balls with a PSI of around 16 – pressures at either end of FA guidelines,'

They found working memory, which allows the brain to briefly hold new information while it's needed in the short term, declined by 20 per cent.

The vast majority of participants who headed the ball (80 per cent) also showed potential signs of concussion – temporary injury to the brain.

Usually after a knock, if the time needed for an athlete to complete the King-Devick test increases by three seconds from their normal values, it’s considered a possible concussion and they are removed from competition.

The increased test times for both the soft ball group (4.32 seconds) and hard ball group (4.57 seconds) were 'so extreme that it would raise suspicion of a concussion in the case of a head injury', the research team say.
