Former football great Austin Robertson Jnr is convinced he now suffers from chronic traumatic encephalopathy (CTE) as a result of repeated head trauma and says he will donate his brain to science.
The 80-year-old, widely considered one of Western Australia's greatest full-forwards, played 269 games for Subiaco and South Melbourne in the 1960s and 70s and was concussed five times during his Aussie Rules career.
