The wife of former Wales defender Keith Pontin has called claims by his former club that his dementia was not caused by playing football an "insult to his memory".
Mr Pontin, who played for Cardiff City between 1976 and 1983 and was capped twice by Wales, was found to have died from dementia caused by him heading the ball repeatedly during his decades-long career.
He had been diagnosed in 2015 and died in August 2020, at the age of 64, just before his 35th wedding anniversary.
