Nijel Amos, a 2012 Olympic silver medalist in the men’s 800 meters, has been banned for three years for doping.’
The runner from Botswana tested positive for the banned substance GW1516 last year in the run-up to the track world championships and received a reduction on the standard four-year ban because he admitted to the charges.
The ban rules Amos out of next year’s Paris Olympics.
Amos equaled the third-fastest time in 800m history at the age of 18 when he won the silver medal behind world record-breaking David Rudisha of Kenya at the 2012 London Games, becoming Botswana’s first-ever Olympic medalist.
His silver medal is not affected by the doping ruling.
The 29-year-old Amos is a three-time Olympian who has won titles at the African Championships and Commonwealth Games.
His time of 1 minute, 41.73 seconds from the 2012 Olympics remains the world junior record.
