Michael O’Reilly, the Irish boxer, has become the first athlete at the Rio Olympics to test positive for a banned substance.
The Portaloise-born middleweight failed a drugs test administered by the Irish Sports Council prior to flying to Brazil with the rest of the Republic of Ireland squad.
O’Reilly has been provisionally suspended from competing at the Games, which officially start on Friday, and is reportedly planning to challenge the decision, according to RTÉ.
