Cuban discus thrower Yarelys Barrios has been ordered to return the Olympics silver medal she won in Beijing eight years ago.

It follows retroactive drug testing of Beijing 2008 samples which showed a positive test for a banned substance called acetazolamide.

As a result, she has been been stripped of her runner-up position and ordered to send back the medal immediately.

But there is a catch.

It appears that a silver medal for the women's discus in 2008 was sold on eBay by a Cuban seller based in Canada in June for just ver €10,000. 

Barrios also won a bronze at London 2012.
