The Greek Olympic Association have reportedly withdrawn Voula Papachristou from the Olympic Games in London.
It is believed that the GOA took the decision following alleged racist comments made by the triple jumper on Twitter.
Papachristou has since apologised for her posts on the social networking site.
However, the GOA believe that her comments warranted a disqualification, according to The AP.
Papachristou had been considered one of nation's best medal hopes heading into the Games.
