 Gold medals for the 2000 Olympic men's 4 × 400 metres relay were awarded to the U.S. squad of Jerome Young, Michael Johnson, Antonio Pettigrew, Angelo Taylor, Alvin Harrison and Calvin Harrison.In 2004, after Young (who ran in the heats) was retroactively banned from 1999 to 2001, all six were stripped of their medals.In 2005, the Court of Arbitration for Sport restored the medals of the remaining five due to the fact that, according to the rules of the time, a team should not be disqualified because of a doping offense of an athlete who did not compete in the finals, but in 2008, Pettigrew admitted to the use of doping from 1997 to 2003, meaning that the team was disqualified.
