Russia's athletes are still unsure whether they will be allowed to compete in the Rio Olympics.
An International Olympic Committee (IOC) panel, which has final say on the matter, has said only that it will make the decision by the end of Thursday, the day before the Games begin.
ITV News Sports Editor Steve Scott reports from Rio de Janeiro.
An International Olympic Committee (IOC) panel of three will have the final say on which Russian athletes can compete at the Rio Olympic Games.
The panel will review all decisions made by international federations, the IOC said Saturday.
Earlier this month the IOC set criteria for Russians to compete in Rio after the sporting world was rocked by revelations of state-backed doping in the country.
More than 250 Russian athletes have so far been cleared to compete in this year's games, which start next week.
IAAF president Sebastian Coe has rejected the Russian government's call for the federation to reconsider its ban on dozens of Russian athletes from competing at the Rio Olympics.
Russian sports minister Vitaly Mutko wrote to the IAAF (International Association of Athletics Federations) after the International Olympic Committee ruled it was up to individual sporting federations to decide if Russia's sportsmen and women should miss next month's Games because of the exposed state-sponsored doping scandal.
Lord Coe's reply said last month's ban of 67 Russian athletes, which followed their individual appeals to the Court of Arbitration for Sport, will be upheld, adding: "There are no grounds for further review."
Five Russian sprint canoeists have been banned from the Olympic Games after being implicated in doping irregularities, the International Canoe Federation has announced.
The ICF ruled five sprint canoeists - Elena Aniushina, Natalia Podolskaia, Alexander Dyachenko, Andrey Kraitor and Alexey Korovashkov - ineligible to compete at the Games, but stopped short of issuing a federation-wide ban.
The governing body of world swimming, FINA, has ruled that seven Russian athletes have been banned from the Rio Olympics for violating rules on doping, according to AP.
Former British Olympian Roger Black has said the International Olympic Committee (IOC) are "passing the buck" by not banning Russia from Rio.
The 400m silver medallist told Good Morning Britain: "If there was ever an opportunity for the IOC to make a stance and say the future of the Olympics is a clean games, it was now.
"Russian athletes are already out in Rio with the less than two weeks to go before the Olympic Games and we don't know who is going to compete.
"What we're watching is an absolute mess and it's an opportunity completely missed."
