It is unclear if the allegations include the 2016 Rio de Janeiro Olympics, where Rahimov took gold with a world-record lift in the men's 77-kilogram class. Rahimov served a two-year ban from 2013-15 in a doping case while competing for Azerbaijan and only returned to represent Kazakhstan a few months before the Olympics.
