Russian swimmer Yulia Efimova could find out tomorrow whether she will be allowed to compete in the Olympic Games here after being barred because of a doping conviction.
The 24-year-old world 100 metres breaststroke champion launched a late appeal to the ad hoc Division of the Court of Arbitration for Sport (CAS) following a decision to leave her off Russia's team for Rio 2016 because of a two-year doping ban.
Her hearing against the Russian Olympic Committee (ROC), International Olympic Committee (IOC) and the International Swimming Federation (FINA) was heard today, CAS announced in a statement.
"A hearing took place today and was adjourned until the afternoon of 2 August 2016; the next steps for this procedurewill be decided then," CAS said in the statement.
CAS also revealed that the Russian Weightlifting Federation have officially appealed against the International Weightlifting Federation's decision to ban the whole team from Rio 2016.
A hearing is due to be held on Wednesday (August 3) and a decision announced later that day.
The 17 Russian rowers, led by Daniil Andrienko, prevented by the International Rowing Federation and the IOC from taking part at Rio 2016 have also lodged an appeal.
They have been barred due to a combination of positive drugs tests, links to the McLaren Report and being unable to prove they were tested outside Russia.
Their appeal is due to take place tomorrow.
Efimova's team-mates Vladimir Morozov and Nikita Lobintsev, banned from Rio 2016 because of their links to the McLaren Report, appeared before CAS yestrday.
The hearing was adjourned for them to provide more information and a decision is due to be made tomorrow about how the hearing will proceed.
CAS revealed that 11 cases have already been registered with them since they opened their office here last Tuesday (July 26).
It means that, in less than a week, the CAS ad hoc Division has registered the same number of applications as for the total period of London 2012.
Russia's double world wrestling champion Viktor Lebedev has also appealed against the decision by the ROC to not pick him because he was included in the McLaren Report.
His case will be heard after a decision made in the Efimova case.
Another Russian double world champion, canoeist Andrey Kraitor, has appealed against the International Canoe Federation decision to stop him competing at Rio 2016.
CAS is also due to hear two cases not involving Russian athletes.
Sprinter Mangar Makur Chuot Chep has appealed against a decision by South Sudan not to select him for Rio 2016.
Jamaica's Commonwealth Games discus silver medallist Jason Morgan is also trying to get a decision not to select him for the Olympics overturned.
