The experts looked  whether or not heading a football could lead to brain damage. The research team looked  the deaths  7,676 ex-soccer players who played in Scotland professionally  1900 and 1976. The team compared the deaths of the former soccer players to the deaths  23,000 people who did not regularly play football. They found that the football players suffered  a lot more brain injuries.
The research was requested  the Football Association and the Professional Footballers' Association  the UK. The two associations made the request  the death  English football player Jeff Astle  2002. Mr Astle's family was convinced he died as a result  playing football. Doctors said his cause  death was "repeated minor brain traumas". The doctors said this could happen  heading a soccer ball.
