The World Anti-Doping Agency will release a new report on December 9 on drug use in Russian sports, building on a landmark report this summer that led to doping bans on dozens of Russian athletes.
Authored by Canadian lawyer Richard McLaren, the investigative report's contents have been kept under wraps. But International Olympic Committee President Thomas Bach said on December 8 that he expects it to pose an "immediate challenge" to global sports.
The committee this week extended sanctions that were imposed as a result of the report in July which prevent Russian track and field athletes from participating in global competitions.
Russia has repeatedly rejected McLaren's accusations of "state-sponsored" doping, which led to the banning of more than 110 Russian athletes at the Rio de Janeiro games in August.
The first report found a "state-dictated fail-safe system" of doping and cover-up at the Sochi Winter Olympics in 2014. The new report is expected to build on those findings.
Russia's new Sports Minister Pavel Kolobkov, a former Olympic champion fencer, said on December 8 that Russia has "declared war" against doping in a bid to regain its reputation and standing in world sports.
