The IAAF said in a statement : 'While the IAAF agrees with RUSADA that there is , in each case , sufficient evidence of an anti-doping rule violation and that there are aggravating circumstances justifying an increased sanction of more than two years , the IAAF disagrees with the selective disqualification of results applied by RUSADA as a consequence of the previous rulings . ' Kirdyapkin was one of six Russian athletes to be banned after abnormalities with biological passports . The IAAF said the case of Tatyana Chernova , who beat Jessica Ennis-Hill to heptathlon gold at the 2011 World Championships but was later banned , was still under review .
