MOSCOW—At least eight Russian athletes are set to miss next month's games in Rio de Janeiro under new IOC rules prohibiting former dopers from competing, Russia's top Olympic official said.
Alexander Zhukov had said earlier that only eight athletes would be affected, but acknowledged after a meeting of his Russian Olympic Committee that the number would rise.
"I think that in the near future we will have full information," Zhukov said. "I had said eight, but it's already clear that it's more."
While Zhukov did not name the athletes, competitors in swimming, cycling and weightlifting are likely to be affected.
Zhukov spoke a day after the International Olympic Committee executive board decided against imposing a complete ban on Russian athletes from the Rio Games over allegations of state-sponsored doping. The IOC asked individual global sports federations to decide on entry of Russian athletes, and announced new eligibility criteria.
The rules prohibit Russia from sending to the Rio Games any athletes who have previously served doping bans. Sports federations can also reject Russian entries if they have not undergone enough international drug testing. Results of Russian tests will not be accepted following allegations of routine cover-ups at Moscow's anti-doping laboratory.
It remains unclear whether there could be legal challenges to the IOC criteria. A similar IOC measure, known as the Osaka Rule, which would have prohibited any athletes who had received doping bans from competing in the subsequent Olympics, was declared invalid by the Court of Arbitration for Sport.
Zhukov said the IOC's latest criteria violated the "principle of equality" because they only applied to Russia, although he has previously ruled out legal action.
However, Andrei Mitkov, the agent of previously-banned world champion swimmer Yulia Efimova, told Russia's Sportbox website that she would apply to CAS if she was not allowed to compete.
Russia's track and field athletes remain barred from the games by the IAAF, a decision upheld last week by CAS and accepted by the IOC.
Now, with the Aug. 5 opening ceremony approaching, it is up to the remaining 27 international sports federations to vet Russian athletes on an individual basis.
The archery federation said Monday it had approved the entry of three Russian archers after determining they have no links to doping.
World Archery said it was satisfied that the three female Russian archers nominated for the games had been tested "extensively" and have never been sanctioned for doping. They were listed as Tuiana Dashidorzhieva, Ksenia Perova and Inna Stepanova.
Archery was not implicated in the World Anti-Doping Agency report released last week by Canadian lawyer Richard McLaren, which accused Russia of covering up doping in 20 summer Olympic sports.
Russian archers have been targeted for additional testing, both in and out of competition, since the report was released, the federation said.
"No Russian archery athlete has received an adverse analytical finding," it said, adding that it would submit its findings to the IOC.
The International Tennis Federation said Sunday it expects Russia's eight-player Olympic tennis team to be eligible for the games. The ITF said the players "have been subject to a rigorous anti-doping testing program outside Russia."
The International Equestrian federation said there was no indication of doping within Russia's five-rider team.
Russian cyclist Ilnur Zakarin, who won a stage during the Tour de France which ended Sunday, could be ruled out because he served a two-year ban after testing positive for a steroid in 2009.
The International Judo Federation, whose honorary president is Russia's President Vladimir Putin, said it has already tested 84 percent of the 389 athletes from 136 countries who are qualified to compete in Rio. It made no mention of the 11 Russian judo athletes entered.
The international gymnastics federation, FIG, said it "has taken note" of the IOC ruling and "shall fully adhere to it." It said it would establish a "pool of Russian eligible athletes." Gymnastics was not mentioned in the McLaren report.
Boxing's governing body, AIBA, said it was examining Russia's entrants. Russia has qualified 11 boxers for Rio, including reigning world champions Vitaly Dunaytsev and Evgeny Tishchenko.
"We are reviewing and analyzing, on a case by case basis, the anti-doping record of the 11 Russian boxers currently qualified for Rio 2016," AIBA said. "This information and the decision of AIBA in respect of the athlete's eligibility will be submitted to the IOC for confirmation in due course."
