The International Olympic Committee (IOC) has opted against imposing a blanket ban from Rio 2016 on Russia, instead opting to allow the fate of the country's competitors to be decided by the international federations for each sport.

Calls for a suspension of all Russians had grown following the publication on Monday of a damning report by Professor Richard McLaren - independently produced at the request of the World Anti-Doping Agency (WADA) - that found doping of the country's athletes had been "directed [and] controlled" at state level.

McLaren's report prompted WADA to recommend that both the IOC and International Paralympic Committee (IPC) decline Russian entries for Rio 2016.

However, the IOC executive board confirmed on Sunday - less than two weeks before the start of the Olympics - that a full ban would not be enforced, instead laying down strict criteria that must be met by any Russian seeking to compete in Rio.

In addition, Russia will not be allowed to enter any athlete who has been banned for doping, regardless of whether they have served the sanction.

Russian track and field athletes are already the subject of a suspension from the IAAF, with the Court of Arbitration for Sport [CAS] having this week rejected an appeal against that ban on behalf of 68 affected individuals.

The IOC also confirmed on Sunday that whistle-blower Yuliya Stepanova will not be allowed to enter the Olympics due to her past doping sanctions. The IAAF had approved a request for Stepanova to compete in Rio as a 'neutral athlete'.
