Calvin and Alvin Harrison serve twin drug bans togetherAlvin Harrison recently created a unique but unwanted piece of history when he was suspended for a period of four years by the United States Anti-Doping Agency after admitting taking a cocktail of banned performance enhancing substances.

Alvin became the second half of the first set of twins to be banned for drugs. His brother, Calvin, was suspended for two years in August for a second doping violation involving the stimulant modafinil.

Alvin Harrison won 4x400m relay Olympic golds at the Atlanta and Sydney Olympic and is the third member of the US relay squad from Sydney to have either failed tests or been banned for doping, the others being his brother Calvin and Jerome Young.
