Ahmed was scheduled to wrestle Devid Safaryan of Armenia, while Emara was slated to face George Gogshelidze of Georgia, both matches at 8:30am.
However, the two players showed up four hours late believing that the match would start at 1pm based the schedule of the previous seven days of Olympic wrestling.
All matches on the final day of the Olympics were pushed up to make room for the closing ceremony.
No immediate official word was available on whether the pair simply failed to turn up on time or were not informed by management about changes in schedule.
