An IOC disciplinary commission put off a hearing into the case from Friday until today because the pair were involved in a mysterious motorcycle crash just hours after missing the village tests and have spent the weekend in hospital.
In a new twist today it emerged that in addition to missing a drugs test in Chicago on August 10 and 11, the sprinter also missed the testers in Tel Aviv on 28 July.
Public opinion here is turning against the stars. Greek President Costis Stephanopoulos has described the case as "a great embarrassment for the Games."
Meanwhile, world 100 metres champion Torri Edwards will also learn today whether she can compete in the Games after a positive test in April. CAS will consider an appeal by the American sprinter against a two-year ban.
