A study has found that one in four young GAA players has continued playing while suffering from concussion.
The survey conducted by NUI Galway spoke with young players aged between 13 and 25 in clubs around the country.
More than 40% of male players wrongly believed that they could overcome the effects of concussion by playing on.
The study, published in the International Journal of Adolescent Mental Health, found more than 50% were not aware of key symptoms of concussion.
