The anatomy of a scandal - 13 days that shattered Ireland's Olympic spirit
The joy and pride provided by the O'Donovan brothers and Annalise Murphy has been completely eclipsed by judging controversies, doping and ticket touting scandals.
Here is how the dark side of Ireland's Olympic adventure has transpired:
August 4: It emerged that Michael O’Reilly failed a drugs test, which was taken in Ireland before he flew to Rio for the Games.
August 5: It was reported that O’Reilly would contest the finding. It was unclear at first if he would request his ‘B’ sample be tested, though initial indications were that he would not.
August 7: In an apparent U-turn, it was reported O’Reilly would request a ‘B’ sample test.
August 5-8: Sources in O’Reilly’s camp repeatedly insisted he was “squeaky clean” in the following days.
August 8: Irishman Kevin James Mallon, a finance director at the THG Group, is arrested ion Rio de Janeiro for alleged ticket touting.
August 9: The OCI announce that they are launching an immediate investigation after it emerges that over 800 tickets involved in an alleged ticket touting scam were allocated to them.
August 9: O’Reilly admitted he “unintentionally” took a supplement which “may” have contained a banned substance. His disqualification was confirmed.
August 10: Junior Sports Minister Patrick O'Donovan said that the touting scandal would form part of the Oireachtas Sports Committee's formal review of Rio 2016.
August 11: Sports minister Shane Ross expresses concerns over OCI's investigation committee and calls for an independent observer to be involved.
August 12: The PRO10 agency, which was contracted as the official authorised ticket reseller (ATR) for the Olympic Council of Ireland (OCI), said Kevin Mallon was holding tickets for its clients.

August 16: Further controversy as Michael Conlan is defeated on a unanimous decision by Russia's Vladimir Nikitin. He brands the AIBA 'cheats' in an explosive post-fight interview. Statistics prove that Conlan should have won.
August 17: AIBA admit that a 'handful' of decisions were 'not at the level expected' and the judges involved will not officiate again in Rio but results stand.
