Doctor Sergei Portugalov was found guilty of several offences by the Court of Arbitration for Sport
One of the key figures behind widespread Russian doping has been banned from sport for life.
Doctor Sergei Portugalov was found guilty of several offences by the Court of Arbitration for Sport (CAS).
He had previously worked for the Russian Athletics Federation. The country is still banned from track and field athletics because of the scandal.
In a statement today, CAS said: "On the basis of clear evidence, Dr Portugalov is found to have violated the following articles of the IAAF Anti-Doping and Medical Rules:
"Article 32.2(f) ["Possession of a Prohibited Substance or Prohibited Method"]
"Article 32.2(g) ["Trafficking or Attempted Trafficking in any Prohibited Substance or Prohibited Method"] and
"Article 32.2(h) ["Administration or Attempted Administration of a Prohibited Substance or Prohibited Method"].
"As a consequence, a lifetime period of ineligibility beginning on 10 March 2017, has been imposed on Dr Portugalov.
"The CAS acted as first instance decision-making authority for this matter, substituting for RusAF, which was suspended at the time the matter was ready to be adjudicated (and which remains suspended)."
