Rio 2016 Olympics: Greek athlete expelled after failed drugs test

The Hellenic Olympic Committee has taken a team of 97 athletes to Rio

An unnamed Greek athlete has been expelled from the Rio Olympic Games after failing a drugs test.

The athlete's A sample tested positive for a banned substance in early July.

Reports suggest that neither the athlete's name nor the sport they compete in will be revealed until their B sample has been analysed.

The athlete left the Olympic village hours before the opening ceremony and is the second to be sent home after an Irish boxer failed a test on Thursday.
