Former Geelong and Essendon ruckman John Barnes is leading a push to sue the AFL and its clubs with relation to the effects of concussion post-retirement.

Barnes is one of roughly 12 former footy players who fear neurological impairments could be linked to countless head knocks suffered while playing the game and are weighing up their legal options, according to News Corp.

The 2000 premiership player will be a lead plaintiff in a proposed Federal Court action with the help of highly-regarded lawyer Greg Griffin and player agent Peter Jess.

Barnes was diagnosed with epilepsy five years ago and has experienced increased memory loss and anger issues. The 48-year-old believes all of those conditions could be linked to his playing days.
