One of the medal favorite Hungarian fencers have missed doping tests three times in the past 12 months and will likely get a two year ban just before the Games. We don't know who this is, the media is making it seem like it's a big name, probably not the biggest (Szilágyi) because that would shock me. So it might be Szatmári, Siklósi, Koch, Pusztai, or Battai...
Edit: I have also seen a rumour that it's Anna Kun in women's epee...
