Russian swimmer Yulia Efimova is likely to find out on Tuesday whether she will be able to compete in the Rio Olympics after her appeal to the Court of Arbitration for Sport (CAS) was adjourned.

Efimova, a four-time world breaststroke champion, was withdrawn from the Games by the Russian Olympic Committee after the International Olympic Committee said all Russians who had previously served a doping ban were barred.

She took the case to CAS and after an initial hearing on Monday, it is likely to be decided on Tuesday.

When that case has been decided, CAS will then rule on wrestler Viktor Lebedev, who has been banned on the same grounds as Efimova, while 17 rowers will also have their appeal heard on Tuesday.

Swimmers Vladimir Morozov and Nikita Lobintsev were among the first athletes to be heard on Sunday and following an adjournment, the case is due to continue on Monday.

The Russian Weightlifting Federation’s appeal against the blanket ban on their athletes will be heard on Wednesday, with a decision expected the same day.

Canoeist Andrey Kraitor is waiting to find out his fate as his hearing against a ban has yet to be scheduled.

CAS are also involved in two cases away from the Russian doping scandal as Sudanese sprinter Mangar Makur Chuot Chep and Jamaican discus thrower Jason Morgan are challenging their non-selections by their respective country’s Olympic associations.

In total there have been 11 cases registered by the Olympic division of CAS since it opened in Rio on July 26, the same number as for the entire period of the 2012 Games in London.
