The IOC approved the entry of 271 Russian athletes for the Rio de Janeiro Olympics on Thursday, meaning 70 percent of the country's original team will compete after a doping scandal that has dominated the buildup to the games.
Also on Thursday, the IOC rule barring Russian athletes with prior doping sanctions from competing in the games was rejected as "unenforceable" by a sports arbitration panel, a decision which could open the door to further appeals and more Russians being entered.
The International Olympic Committee announced the go-ahead for 271 Russian athletes about 24 hours before the opening ceremony of the games. Overall, more than 100 Russians have been excluded, including 67 in track and field.
The IOC recently rejected calls from anti-doping organizations to ban Russia's entire team following a report by a World Anti-Doping Agency investigator that detailed evidence of state-directed doping and cover-ups.
Instead, the IOC asked international federations to examine individual Russian athletes to determine if they should be eligible for the games. The IOC set up a panel of three executive board members to review the entries and make the final call, taking into account the advice of an independent sports arbitrator.
After the review, the IOC declared in Thursday's statement: "271 athletes will form the team entered by the Russian National Olympic Committee from the original entry list of 389 athletes."
Russian Olympic Committee president Alexander Zhukov told reporters earlier that 271 of his country's athletes had been cleared.
Several international federations announced separately Thursday that they had received the final approval for Russian entries in their events, including boxing, judo, equestrian, volleyball and golf.
Russia's track and field team remains barred following an earlier decision by the IAAF. Only one athlete, U.S.-based long jumper Darya Klishina, was cleared by the IAAF because she had been regularly tested outside Russia.
