Professional rugby players are being urged to donate their brains to science when they die, in the hope it will improve understanding of brain injury in the future.
Boston University School of Medicine professor Robert Cantu told the Scotsman that he expects rugby players to exhibit similar damage to that seen in American football players.
The problem is, he has yet to examine the brains of rugby players.
"Rugby as a sport should encourage its athletes, especially athletes who have had issues later in life, to donate their brain upon death for study and be assessed," he told the newspaper.
Chronic Traumatic Encephalopathy (CTE) is a condition which is increasingly being linked to cognitive decline in athletes prone to head trauma during their careers.
The progressive degenerative disease is thought to manifest itself in the degeneration of brain tissue and a build-up of an abnormal protein known as tau.
