Ryan Mason insists he would not be surprised if heading no longer exists within football in about 10 or 15 years time.
Mason, who played for both Tottenham and Hull as a midfielder, was forced to retire from football after fracturing his skull back in 2017 after a sickening clash of heads with Chelsea's Gary Cahill at Stamford Bridge.
Dr Willie Stewart's FIELD study recently showed that footballers were three and a half times more likely to die of a neurodegenerative disease than the general population.
And 29-year-old Mason believes heading may soon not be part of the game amid the 'shocking' and 'concerning' research.
