Usain Bolt was stripped of a 2008 Beijing Olympic gold medal on Jan. 25 because his Jamaican teammate Nesta Carter retroactively tested positive for a substance banned by the Games.
A reanalysis of Carter's urine and blood samples by the International Olympic Committee found methylhexaneamine, an energy-boosting ingredient, notes The Telegraph.
Carter ran the first part of 4x100m relay race, which helped the Jamaican team -- Carter, Bolt, Michael Frater and Asafa Powell -- win.
That victory was the first step in Bolt's perfect "triple-treble" record of gold medals in the 100m, 200m and 4x100m relay in 2008, 2012 and 2016.
Carter did not compete in the Rio 2016 games as he was trying to clear his name after coming up on a provisional list of failed retests.
As a result of the Jamaican team being stripped of their gold medals, the second-place Trinidad and Tobago team is likely to be awarded the gold from 2008, while third-place Japan will probably be given the silver and Brazil will receive the bronze.
Bolt told The Guardian in June 2016 that he would return his medal if Carter retested positive:
It’s heartbreaking because over the years you’ve worked hard to accumulate gold medals and work hard to be a champion -- but it’s just one of those things. Things happen in life, so when it’s confirmed or whatever, if I need to give back my gold medal I’d have to give it back, it’s not a problem for me.
The International Association of Athletics Federations announced on Jan. 25, 2017, that any other samples Carter has given will be retested, which could mean more bad news for Bolt if Carter comes up positive for the London 2012 Olympics:
Once the IOC’s case and any appeal is concluded for the disqualification of Nesta Carter from the men’s 4x100m event at the Olympic Games Beijing 2008 for an anti-doping rule violation, the IAAF will take it to the Jamaican federation to determine Carter’s sanction beyond this disqualification. The IAAF will also retest any samples it holds in storage for the athlete from other competitions.
