Kazakhstan's Nijat Rahimov stripped of Rio 2016 Olympic gold medal and banned

The 2016 Rio Olympics weightlifting gold medal was stripped from Nijat Rahimov after he was found guilty of using a banned substance.

Four times, under weightlifting anti-doping rules, Rahimov used a prohibited method, and he was found guilty.

All of his results from March of 2016 have been removed.

The world champion was banned for two years after testing positive for steroids.

A year later, he won the -77 kilogram division in Rio and set a world record in the clean and jerk.

The International Testing Agency served a notice of charge on Nijat Rahimov after the World Anti-Doping Agency launched an investigation into sample collection practices in the sport of weightlifting.

The International Weightlifting Federation's anti-doping rules state that the use of a prohibited method and four urine substitutions constitute anti-doping rule violations.
