Russian athlete Ksenia Savina, 29, has been suspended for 12 years after she was found to have used banned drug last year for athletics competition.
Savina used blood-boosting hormone EPO.
Russia has been rocked by several sporting bans.
International investigations have found evidence of widespread, state-sponsored doping in athletics and other sports in recent years.
She claimed in the medical documents it was her coach and husband, Alexei Savin, who needed the medication for chronic renal failure that must have been mixed up with her back pain medication.
The investigation by Russian anti-doping agency (RUSADA) showed the documents had been forged.
The ban has ended her career.
The athlete’s husband and coach received a four-year ban for violating anti-doping regulations.
Russian anti-doping agency RUSADA and Russia’s athletics federation were suspended after a 2015 report by the World Anti-Doping Agency (WADA).
The World Anti-Doping Agency stated in the report, evidence of state-sponsored doping in Russian athletics was found.
The Russian anti-doping agency (RUSADA) was reinstated last year.
