Unnamed Greek athlete expelled from Rio Olympics after failing drug test

A Greek athlete has been expelled from the Rio Games after failing a drugs test, Greece's Olympic Committee said on Friday.

The unnamed individual's A sample tested positive for banned substances in a pre-Olympics test conducted in July in Athens.

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 has left the Olympic Village and is the second to be sent home from Rio, after an Irish boxer failed a test on Thursday.
