The biggest drug scandal in AFL history has finally drawn to a close, with 34 past and present Essendon players found guilty of using a banned substance thymosin beta-4 by WADA. Essendon will lose a huge chunk of its playing list for the 2016 season, plus there will be question marks over the legitimacy of Captain Jobe Watson winning the games top individual honor (the Brownlow Medal) during the period of doping in question (and if he gets to keep it). 
http://www.abc.net.au/news/2016-01-12/cas-upholds-wada-appeal-essendon-anti-doping-verdict/7081874The Court of Arbitration for Sport has upheld WADA's appeal of the AFL anti-doping tribunal's Essendon verdict, with 34 past and present Bombers players banned for 12 months, which means they will miss the entire 2016 season.
The club confirmed the ban on Tuesday morning.
"Regrettably we can confirm the Court of Arbitration for Sport has found 34 past and present players guilty of committing an anti-doping rule violation," club chairman Lindsay Tanner said in a statement.
"As a result, the players - including 12 currently listed with Essendon - have been suspended for the 2016 season. The club is currently digesting the decision and we will provide a further update later today."
Last March, the tribunal found the 34 were not guilty of using a banned substance thymosin beta-4, relating to the club's 2012 supplements program, led by controversial sports scientist Stephen Dank.
ASADA, who had brought the case, chose not to appeal the decision, but WADA exercised its right to appeal, leading to a hearing in Sydney last November.
There are currently 12 of the original 34 still on the books at Essendon - including captain Jobe Watson and vice-captain Dyson Heppell.
The other current players affected are Michael Hurley, Cale Hooker, Michael Hibberd, Brent Stanton, Travis Colyer, David Myers, Tom Bellchambers, Heath Hocking, Ben Howlett and Tayte Pears.
Watson and the now-retired Dustin Fletcher will reportedly served bans eight days longer than the remaining players as a result of playing for Australia in the 2015 international rules series.
Five other players are at other clubs - Paddy Ryder and Angus Monfries at Port Adelaide, Stewart Crameri with the Western Bulldogs, Jake Carlisle at St Kilda and Jake Melksham at Melbourne.
WADA released a statement on Tuesday confirming the basis of the bans.
"The appeal filed by WADA against the Australian Football League (AFL) Anti-Doping Tribunal's decision of 31 March 2015 is upheld and the appealed decision is set aside," WADA said.
"The 34 players concerned are sanctioned with a period of ineligibility of two years, commencing on 31 March 2015, with credit given for any individual period of ineligibility already served.
"Thus, most of the suspensions will come to an end in November 2016."
WADA's statement said that the CAS panel found "to its comfortable satisfaction" that clause 11.2 of the 2010 AFL anti-doping code had been violated, and found by a majority that "all players were significantly at fault".
The verdict also raises questions over the 2012 Brownlow Medal victory of Essendon skipper Watson.
The three-year saga has led to a number of senior figures leaving Essendon, including the former chief executive Ian Robson, former chairman David Evans and his replacement Paul Little, and former coach James Hird.
Hird was banned for 12 months in 2013 when the AFL fined the club $2 million and kicked the Bombers out of that year's finals series.
Hird returned after the conclusion of his ban, but he resigned in August last year to allow the Bombers to have a fresh start under a new coach.
More to come.
