Aquatics to wrestling - How each Olympic sport has reacted to Russian doping scandal
The International Olympic Committee's decision to put the participation of Russian athletes in Rio into the hands of their respective sports' international federations has yielded some big decisions with the Games just 10 days away.
Here,we collate the current view, where possible, of each Olympic sport in turn - with the exception of football and rugby sevens, in which no Russian athlete had been scheduled to take part.
AQUATICS: Governing body FINA will subject the eligibility of Russian swimmers to "specific additional criteria", and approve only those who were subject to "reliable anti-doping scrutiny". Seven Russian swimmers who already fail to meet the criteria have been withdrawn, including four-time world champion Yulia Efimova. FINA says Russian synchronised swimmers, divers and water polo players are not implicated.
ARCHERY: World Archery say Russia's three qualified archers have been "tested extensively" and can compete in Rio. They add: "The IOC executive board should be congratulated on its courageous decision not to put a blanket ban on the Russian Federation".
ATHLETICS: The IAAF has banned all Russian track and field athletes from competing in Rio, with the exception of those who can prove they have been rigorously tested outside Russia. Only two have passed the test to date - and they will compete as neutrals.
BADMINTON: Four Russians have qualified. No response from the World Badminton Federation (BWF).
BOXING: Governing body AIBA is "reviewing and analysing, on a case-by-case basis, the anti-doping records of the 11 Russian boxers currently qualified for Rio".
CANOEING: Nineteen Russian canoeists have qualified in sprint and slalom. Their places are currently under review by the International Canoe Union (ICU).
CYCLING: No confirmation over Russia's 17-strong cycling team yet, but UCI president Brian Cookson says: "It would be difficult for us to ban an entire team."
EQUESTRIAN: Ingmar De Vos, president of the International Equestrian Federation (FEI) says: "There is no indication of any organised doping malpractices within the Russian equestrian delegation... (so) I see absolutely no reason why the (five) Russian equestrian athletes should not compete at Rio."
FENCING: Russia has qualified a full team of 16 fencers. Their places are currently under review by the International Fencing Federation (FIE).
GOLF: World number 338 Maria Verchenova is the only Russian golfer in Rio. No response yet from the sport's Olympics-affiated body, the International Golf Federation (IGF).
GYMNASTICS: The International Gymnastics Federation (FIG) is hoping "as soon as possible" to "establish the pool of Russian eligible athletes". Russia has announced a team of 20 for the Games.
HANDBALL: The International Handball Federation (IHF) has requested "urgent" information regarding the current location of the Russian women's team in order that its 14 players can be tested "as soon as possible".
JUDO: International Judo Federation (IJF) president Marius Vizer says: "The presence of (11) Russian athletes is very important... we hope that by allowing participation of Russian athletes in Rio 2016, we will send out a positive message to all the young people who deserve to be given examples of friendship instead of examples of Cold War."
MODERN PENTATHLON: The sport's governing body, the UIPM, has indicated it will make a decision on the participation of the four qualified Russian athletes "in the next couple of days".
ROWING: Governing body FISA on Monday banned three of the 28 Russian rowers who have qualified. They are Ivan Balandin from the men's eight, who was named by Richard McLaren, and Anastasiia Karabelshchikova and Ivan Podshivalov, who have previously served doping bans. But it said more bans could follow when the analysis of anti-doping samples from all the rowers is completed on Tuesday.
SAILING: No comment yet from the International Sailing Federation (ISF), but the All-Russia Sailing Federation says: "The international federation has no claims to us and the (seven-strong) Russian team will compete in its full composition in Rio."
SHOOTING: Eighteen athletes named. No response from the International Shooting Federation (ISSF).
TABLE TENNIS: The International Table Tennis Federation (ITTF) "is investigating table tennis' involvement in the McLaren report and will make a decision by Wednesday if the three qualified Russian table tennis players can compete at the Rio 2016 Olympic Games".
TAEKWONDO: Three Russian athletes qualified. No response from the World Taekwondo Federation (WTF).
TENNIS: The International Tennis Federation (ITF) says Russian players nominated for Rio have already been subject to a total of 205 drugs tests since 2014, and will be allowed to play.
TRIATHLON: Six Russian athletes qualified. No response from the International Triathlon Union (ITU).
VOLLEYBALL: No ban. Governing body the FIVB says: "Russian athletes have been tested at the same level as all other countries and the majority of the testing analysis of Russian athletes has been conducted outside of Russia."
WEIGHTLIFTING: Russia initially qualified a full quota of six men and four women, but it was reduced to five and three by the International Weightlifting Federation (IWF) in June due to multiple doping violations. Reports suggest the whole Russian team could be banned, but the IWF were unavailable for confirmation.
WRESTLING: Seventeen Russian wrestlers involved. No response from United World Wrestling, but highly unlikely to face sanction.
