Usain Bolt‘s 4x100m relay gold from the 2008 Olympics is in jeopardy following the announcement that Jamaican teammate Nesta Carter tested positive for a banned substance at the Beijing Games. Carter was part of the men’s 4x100m relay-winning team that included Bolt, the world’s fastest man.

Carter is reported to have tested positive for the drug methylhexanamine, which is on the World Anti-Doping Agency’s banned substances list. The drug is considered a stimulant.

If Carter’s “B” sample tests positive, all four members of the team could lose their Olympic gold. Bolt, the world record holder in the 100m, 200m and 4x100m, ran the third leg of the relay, which also included Asafa Powell and Michael Frater. Bolt won two additional golds at the 2008 Olympics and won three golds in London in 2012, known as the triple-double.

Bolt, 29, will represent the Caribbean nation at the 2016 Rio Olympics.

Carter’s positive test comes as part of 454 samples which were retested by the World Anti-Doping Agency in an effort to catch dopers. The Russian athletics federation is currently suspended from competing in international events because of its involvement in performance-enhancing drugs and under threat of missing the Olympics.

Kenya’s participation at the Rio Olympics was too in question but the International Olympic Committee announced that the African distance running powerhouse would be allowed to send athletes to Brazil in August.
