Australian football great Gary Ablett Snr has launched legal action against the AFL and two of his former clubs, Hawthorn and Geelong, over concussions he suffered during his career.
Lawyers acting for the 61-year-old said he underwent a scan last year which revealed brain damage.
The writ lodged by his lawyers claims the league and Ablett's former clubs "knew or ought to have known of the potential long-term consequences of concussion suffered by the plaintiff".
