A former Essendon player has lodged paperwork with the Victorian Supreme Court to begin legal action against Essendon and the AFL.
The player, who AFL.com.au has chosen not to name, has requested his name be suppressed during the trial.
Essendon had no comment when contacted by AFL.com.au.
An AFL Anti-Doping Tribunal is due to hand down findings on charges against 34 past and present Essendon players on March 31.
The Tribunal has also heard evidence against former Bombers sports scientist Stephen Dank.
The allegations before the Tribunal relate back to the alleged use of banned peptide Thymosin beta-4 back in the 2012 season.
Essendon self-reported to the AFL and ASADA in February 2013.
The club was banished from the 2013 finals series, fined $2 million and coach James Hird suspended as a result of an AFL Commission hearing into governance issues at the club.
