Nesta Carter
Jamaican team originally won gold medals in Men's 4 × 100 m relay but was disqualified due to anti-doping rules violation by Nesta Carter. The Court of Arbitration for Sport decided in 2018 that Trinidad and Tobago is the winner, the silver medal was reallocated to Japan and the bronze to Brazil team, which was formed by sprinters Vicente de Lima, Sandro Viana, Bruno de Barros and José Carlos Moreira.
