Nesta Carter
On 25 January 2017, the Jamaican team was stripped of the gold medal place due to Nesta Carter testing positive for the prohibited substance methylhexaneamine. The IOC requested that the IAAF modify the results, and, after CAS dismisses the appeal of Jamaican sprinter, the medals were redistributed accordingly. Trinidad and Tobago team was advanced to gold, Japan to silver, and Brazil to bronze.
