A scathing report outlining a state-sanctioned doping system in Russia prompted immediate calls for the nation's entire team to be sidelined from the Summer Games, raising the possibility that the Olympics could go on without a sports superpower for the first time since the 1980s.
The investigation released Monday confirmed a scheme run out of the anti-doping lab in Moscow that ensnared 28 summer and winter sports, from track to snowboarding to table tennis. It lasted at least four years and involved at least 312 positive tests that went unreported at the behest of higher-ups in the country's sports ministry.
