The panel will review all decisions made by international federations, the IOC said Saturday.

"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."

The International Tennis Federation (ITF) has said that seven Russian tennis players are eligible to compete in the Rio Games after "rigorous" anti-doping testing.
The ITF welcomes the decision of the IOC to permit clean athletes to compete in Rio 2016 and to let each International Federation determine the eligibility of its respective Russian athletes. The seven Russian tennis players who have been nominated to compete in Rio have been subject to a rigorous anti-doping testing programme outside Russia.
The ITF believes that this is sufficient for the seven Russian tennis players to meet the relevant requirement of today’s decision of the IOC Executive Board.
The ITF believes it is right that clean athletes are permitted to compete in Rio 2016 and looks forward to welcoming the Russian tennis players, along with all other nominated athletes, to Rio.
