We are told by a learned bloke named Robert Cantu, professor of neurosurgery at the Boston University School of Medicine that heading a football can cause hidden trauma following repeated concussions, such as chronic traumatic encephalopathy. The professor reckons, amongst many other conclusions, that the science is not specific enough to demand that heading be banned, but that instead of starting off by heading a soccer ball, young players should practice heading with a beach ball.
Which is maybe the advice which should have been given to Blackburn Rovers striker Anthony Stokes, who attacked an Elvis Impersonator, and has been ordered to pay him €230,000 for headbutting him in a nightclub.
Stokes had already agreed to give his victim €30,000 for breaking his nose and two of his teeth and faces the second payout after being sued in the High Court in Dublin.
Former car park attendant Anthony Bradley, 53, was attacked by Stokes in the VIP section of what was then Buck Whaleys nightclub on Leeson Street in Dublin on June 8, 2013.
The not-so-cocky-now footballer, who has six Scottish league title medals with Celtic and nine Republic of Ireland caps, was hit with a two-year suspended sentence earlier this month after admitting the assault.
