Seven Russian swimmers have been barred from the Rio de Janeiro Olympics, including three linked to recent allegations of a major doping coverup by Russian authorities, world swimming’s governing body FINA said Monday.

Reigning world 100-meter breaststroke champion Yulia Efimova is among four Russian swimmers withdrawn by the Russian swimming federation because they previously served doping bans, FINA said. The others are Natalya Lovtsova, Anastasia Krapivina and Mikhail Dovgalyuk.

The International Olympic Committee on Sunday said Russian athletes with previous doping bans would be banned from the Rio Games. That followed the IOC’s decision not to ban the entire Russian team over allegations of state-sponsored doping.

FINA said three more swimmers were identified by World Anti-Doping Agency investigator Richard McLaren when he examined evidence that Russian government officials ordered the cover-up of hundreds of doping tests.

They are 2008 Olympic silver and 2012 bronze medalist Nikita Lobintsev, bronze medalist Vladimir Morozov and world junior record holder Daria Ustinova.

Russia’s top Olympic official, Alexander Zhukov, told Russian agency R-Sport that he now believed a total of 13 Russians would be ineligible due to previous doping bans. They would be withdrawn from the team, he added.

The 13 are likely to include athletes in swimming, cycling, weightlifting, wrestling and rowing.

On Sunday, the IOC’s executive board asked individual global sports federations to decide on the 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 also can reject Russian entries if they have not undergone enough international drug testing.

• Russian doping whistleblower Yulia Stepanova is appealing her ban from the Olympics, saying it was based on incorrect information and dubious legal grounds.

Stepanova, an 800-meter runner, sent a letter to the International Olympic Committee contending she never said she wouldn’t compete for the Russian team, as the IOC stated. The IOC would not make any exception for her to compete under a neutral flag.

She says the IOC’s ban of any Russian athlete who has previously served a doping ban is not permitted — a ruling the Court of Arbitration for Sport made in 2011.

Etc.

•â€¯Despite a delay of several days, the head of the Australian delegation said she expects her 700 athletes and officials to move into housing at the Rio de Janeiro Olympics on Wednesday.

Australia refused to check in at the Athletes Village when it officially opened on Sunday, complaining about water leaks, gas leaks, electrical faults and filth that delegation head Kitty Chiller said “endangered” athletes.

Chiller said Monday, “It looks we will be able to move everybody in on Wednesday.”
