Essendon Football Club supplements saga

The Essendon Football Club supplements saga was a sports drug doping controversy that occurred during the early- and mid-2010s. It centred around the Essendon Football Club, nicknamed the Bombers, a professional Australian rules football club based in Melbourne and playing in the Australian Football League (AFL). The club was investigated starting in February 2013 by the Australian Sports Anti-Doping Authority (ASADA) and the World Anti-Doping Agency (WADA) over the legality of its supplements program during the 2012 AFL season and the preceding preseason. After four years of investigations and legal proceedings, thirty-four players at the club were found guilty of having used the banned peptide Thymosin beta-4 and incurred suspensions.

The initial stages of the investigation in 2013 made no findings regarding the legality of the supplements program. Still, they highlighted a wide range of governance and duty-of-care failures relating to the program. In August 2013, the AFL fined Essendon $2 million, barred the club from the 2013 finals series, and suspended senior coach James Hird and general manager Danny Corcoran as a result of these findings.

The second phase of the investigation resulted in thirty-four players being issued show cause notices by ASADA and infraction notices by the AFL in 2014, alleging the use of Thymosin beta-4 during the 2012 season. After facing an AFL Tribunal hearing in the 2014/15 offseason, the players were initially found not guilty. The decision was then appealed by WADA to the Court of Arbitration for Sport (CAS), which returned a guilty verdict on 12 January 2016. The guilty verdict was unsuccessfully appealed in the Federal Supreme Court of Switzerland.^[1] The thirty-four players were suspended for two years, affecting seventeen still-active AFL players who missed the 2016 season as a result of the findings.
