The International Paralympic Committee has ordered a re-run of last night's T54 womens's 5000m final on the track at the main stadium after a dramatic crash on the penultimate lap.
Six of the 11 athletes in the field were left felled and 3 countries protested against the result, and the athletes have been told to return their medals.
The race is now set to be re-scheduled for Friday morning.
According to an IPC spokesman, the countries involved - USA, Switzerland and Australia - all appealed against different elements of the race.
A jury of appeal made the decision to overturn the result and order a re-run of the race and under the rules of the IAAF, the decision cannot be overturned.
