Late last year, the World Anti-Doping Agency released a bombshell report detailing all manner of doping, bribing, and cover-ups by Russian track and field athletes, the Russian federation, and the Russian government. Russia received an indefinite ban from track and field for their wrongdoing, and could miss the 2016 Rio de Janeiro Olympics.
But the Russians weren’t the only guilty party. WADA’s report noted that prior to the 2012 London Olympics, 14 Russian athletes had abnormal blood profiles. While four of them were sanctioned, 10 received “unexplained and highly suspicious delayed notifications” from the International Association of Athletics Federations, allowing them to compete.
