MONTREAL (Reuters) - Dick Pound, the former World Anti-Doping Agency (WADA) chief who headed an independent commission that uncovered evidence of state-sponsored doping in Russia, says new allegations of a drugs cover-up at the Sochi Olympics may be hard to prove.
WADA meetings of its executive committee and foundation board on Wednesday and Thursday have taken on new urgency after whistleblower Vitaly Stepanov said the former head of Russia's drug testing lab told him that at least four Russian gold medal winners at the 2014 Winter Games were using steroids.
